Table 1-1. Installation Troubleshooting
Solution
The board’s power LED does not
light when the power supply is
turned on.
The black MicroPower Off button, SW5,
needs to be pressed after power-up.
The board’s power LED does not
light even after the MicroPower Off
button, SW5 is pressed.
Check power supply connections at P25
and P26.
The red power LED is on but I see
nothing on the VGA monitor and
do not hear any beeps from the
speaker nor hear the head
synchronization on the disk drive.
Ensure processor reset by pressing the red
Reset button, SW2.
I hear a beep on the speaker but see
nothing on the VGA monitor.
Check that the monitor has AC power.
Check that the monitor is correctly
connected to the VGA display adapter.
Check that the display adapter is correctly
seated in the ISA slot.
I get the startup message on the
monitor but it says there’s a CMOS
checksum error and doesn’t finish
booting.
This is the normal condition after powerup. The ÉlanSC310 microcontroller
evaluation board’s CMOS RAM does not
have battery backup. Follow the BIOS’
instructions to run the Setup utility to
configure the CMOS RAM. Once
configured, the CMOS RAM can be saved
by leaving the power supply on but using
the MicroPower Off button, SW5, to
power down the board.
I’ve configured the CMOS RAM
but I don’t hear any sound from the
disk drive and the system does not
boot from the diskette.
Check that the 34-wire cable to the disk
drive is properly connected at both the
disk-drive end and the board end (board
connector P27). Check that the CMOS
setup indicates that drive A is a 3.5"
1.44 Mbyte drive.
I hear the diskette being accessed
but get an error message "Non
System disk".
Check that the diskette in the drive is
indeed bootable, just as you would on a
standard PC.

Connecting an IDE Hard Drive
This section describes how to connect an IDE hard drive to the ÉlanSC310
microcontroller evaluation board. You need to provide the following additional
items:
• An IDE-compatible hard drive of size not more than 512 Mbyte. See the
appendix “Verified Peripherals” on page B-1 for a list of hard drives that are
known to work. Note that Connor and Fujitsu hard drives do not work with the
ÉlanSC310 microcontroller evaluation board.
1.0
• A standard 40-wire AT IDE cable.
Assuming you have successfully booted to DOS from a disk drive as described in
“Booting DOS From a Diskette” on page 1-2, do the following:
1. Disconnect power by unplugging the PC power supply from the AC outlet.
!
WARNING: If the PC power supply is on but the board
has been put in a standby mode using the MicroPower Off
button, there is still some power on the board. Completely
unplug the power supply before continuing.
2. Inspect the 40-wire IDE cable that you are providing. The red wire along one
edge of the ribbon cable indicates wire 1. Connect one end of the 40-wire IDE
cable to the hard drive just as you would for a standard PC installation. The
hard drive documentation should indicate where to put wire 1. Connect the
other end of the 40-wire IDE cable to the 40-pin connector P28 on the
ÉlanSC310 microcontroller evaluation board with wire 1 toward the ROM
sockets.
ÉlanSC310 Microcontroller Evaluation Board User’s Manual
1-7
evalbd.book : ch1 Page 8 Thursday, August 8, 1996 2:34 PM
3. Find one of the 4-wire power connectors from the PC power supply and attach
it to the 4-pin connector on the hard drive just as you would for a standard PC
installation. The hard drive documentation should indicate the proper
orientation of the power cable.
4. Apply power to the ÉlanSC310 microcontroller evaluation board by connecting
the PC power supply to an electrical outlet. Then press the black MicroPower
Off button, SW5. The red LED should now be lit.
5. Press the red Reset button, SW2. You should see the BIOS boot message on
the monitor. When booting after a power-up, the CMOS ROM is not configured
and you need to use the BIOS setup utility. Follow the instructions shown on
the monitor to enter the Setup utility.
7. Whether or not your hard drive contains an already installed bootable disk
image (written from some other PC), you should still keep your bootable
diskette in the A drive and boot from that. After you boot properly from A, try
to do a directory listing of C. If the directory listing of C works, you can try
removing the diskette from A and booting from C (Ctrl-Alt-Delete). Note that
not all BIOS’ have the same mapping of logical to physical sectors on a hard
drive, so if your hard drive was written by the BIOS on some other computer,
it may not be readable by the BIOS on the ÉlanSC310 microcontroller
evaluation board. If you are unable to boot from C, you should reformat the
hard drive for use on the ÉlanSC310 microcontroller evaluation board (see your
DOS documentation for how to reformat your hard drive).
1-8
ÉlanSC310 Microcontroller Evaluation Board User’s Manual

6. In the BIOS setup utility, you need to configure Drive C for the proper number
of heads, cylinders and sectors. (Some BIOS products have an AutoDetect
feature that automatically detects this information; some require you enter this
information manually.) You should be able to get these numbers from your
hard drive documentation. Follow the prompts to save this configuration and
exit the BIOS setup utility.

Evaluation Board Restrictions
• The evaluation board ISA bus can only run at 5 V. In normal designs this is not
a restriction.
• The DRAM SIMM modules must have a 70-ns or less RAS access time, for 33
MHz operation.
• The DRAM on the SIMM modules must be x4, x8 or x16. The ÉlanSC310
microcontroller cannot drive x1 DRAM due to the large capacitance associated
with 32 loads.
• System DRAM population of both the 30-pin SIMM sockets and the 72-pin
SIMM socket is not supported simultaneously.
• On the 72-pin SIMM socket, only 16-bit SIMM modules are fully supported.
32-bit SIMMs can be used in the 72-pin SIMM socket but only half of the
memory will be visible.
• The BIOS ROM sockets (U20 and U59) can only be populated with the
following (the AMD recommended part is also listed):
–
–
–
–

256Kx8 Flash (AMD 12-V 28F020 or 28F020A)
ÉlanSC310 Microcontroller Evaluation Board User’s Manual
1.0
• Software cannot be used to switch between ISA and local bus configurations.
One of the configurations must be set up before power-up.
evalbd.book : ch2 Page 5 Thursday, August 8, 1996 2:34 PM
• Application (DOS) ROM space is 16-bits wide (two or four devices must be
used).
• The DOS ROM sockets (U16–U19) can only be populated with the following
(the AMD recommended part is also listed):
– 256Kx8 ROM/EPROM (AMD 27C020)
– 512Kx8 ROM/EPROM (AMD 27C040)
– 256Kx8 Flash (AMD 12-V 28F020 or 28F020A)
NOTE: 512Kx8 Flash can be supported after a minor board rework. Contact
your AMD FAE for more information.
• Some ISA signals are not available when using Local Bus mode. Refer to the
ÉlanSC310 Microcontroller Data Sheet and Programmer’s Reference Manual
for detailed information on the ÉlanSC310 functionality.
• The RTC RAM (integrated in the ÉlanSC310 microcontroller)—which is used
to maintain time, date and system configuration data—is cleared (lost) when
power is removed from the VCC & AVCC power planes.
1.0
• Connectors are available to test local bus operation and modes. However due
to bus loading, High Speed operation is not possible without depopulating
several components.
BIOS
The ÉlanSC310 microcontroller evaluation board comes with SystemSoft BIOS
programmed into the ROM in socket U20, and PhoenixPICO BIOS programmed
into the ROM in socket U59. Jumper JP32 selects which ROM socket is used when
the system boots (JP32 =1-2 selects socket U59, JP32=2-3 selects socket U20).
Each BIOS is an evaluation version specific to the evaluation board.
An evaluation diskette for each BIOS is shipped with your kit. The BIOS ROM
images are located on their respective diskettes.
NOTE: These are evaluation BIOS’ only. Each BIOS has been tested on the
evaluation board and a list of know errata is available on the AMD Utilities diskette.
For the most recent errata listing, contact your local AMD representative.

evalbd.book : ch2 Page 6 Thursday, August 8, 1996 2:34 PM
SystemSoft BIOS
On system power-up, the SystemSoft BIOS tests the system and determines if there
are any problems with the setup configuration. Since there is no CMOS backup
power on the evaluation board, it uses the default BIOS settings upon initial powerup.
NOTE: You need to run setup each time the system is powered off and on again.
SystemSoft BIOS also monitors the Valid RAM and Time (VRT) bit in the RTC.
This bit gets reset every time a hardware reset occurs. Therefore, every time the
system is reset using the red Reset button, SystemSoft BIOS flags a setup error. If
this occurs, press F1 to continue booting with the previous setup information.
SystemSoft has a familiar menu-driven setup screen. The options are listed in the
table below. The default options are indicated in bold.

PhoenixPICO BIOS
On system power-up, the PhoenixPICO BIOS tests the system and determines if
there are any problems with the setup configuration. Since the evaluation board
does not have CMOS back-up power, it uses the default BIOS settings on initial
power-up. The user therefore needs to run setup each time the system is powered
off and then on again.
BIOS prompts the user to press F2 to enter Setup mode and display the setup screen.

Bus Modes
The ÉlanSC310 microcontroller allows designs to utilize two different bus options:
ISA or Local Bus. While in ISA mode, all of the device’s ISA bus signals are
available (refer to the ÉlanSC310 Microcontroller Data Sheet for a detailed
description of the ISA bus). Local Bus mode provides a 386 local bus in addition
to a subset of ISA bus signals. Refer to the ÉlanSC310 Microcontroller Data Sheet
for a description of the signals available in each of these modes.
The ÉlanSC310 microcontroller evaluation board allows testing in each of the two
bus modes available from the ÉlanSC310 microcontroller. Bus mode selection
must be made before applying power to the board and cannot be changed while
the board is in operation. Selection of the bus mode is determined by the resistor
packs labeled RP1, RP2, RP5, and RP6 (see Table 2-7).
1.0
When adjusting the Bus mode jumpers, be sure to follow pin 1 designations. Pin 1
on the resistor packs must correspond to pin 1 on the evaluation board. JP16–JP18
must be set based on what bus mode is selected (see Table 2-7).

a full ISA bus. Some signals are not available, therefore some ISA cards may not
function properly on the evaluation board (refer to the ÉlanSC310 Microcontroller
Data Sheet for a detailed description of the ISA bus). The ISA bus is wait-state
programmable (refer to the ÉlanSC310 Microcontroller Programmer’s Reference
Manual for details on programming ISA bus timings).

Memory
The ÉlanSC310 microcontroller evaluation board supports up to 16 Mbyte of
memory in two different formats: 72-pin, 16-bit SIMM; or 30-pin, 8-bit SIMMs.
Only one of these options can be used at a time. (That is, if the 30-pin DRAM
sockets are used, the 72-pin DRAM socket must be empty. If the 72-pin DRAM
socket is used, the 30-pin DRAM sockets must be empty.)

ÉlanSC310 Microcontroller Evaluation Board User’s Manual
1.0
The ÉlanSC310 microcontroller evaluation board provides a proprietary local-bus
connector for testing of local-bus designs. Since this connector is not standard, a
custom interface is required to test the local-bus functionality of the ÉlanSC310
microcontroller on the evaluation board. In Local Bus mode, some of the ISA bus
signals are lost. Refer to the ÉlanSC310 Microcontroller Data Sheet for more
details on what signals are available in this mode. Since different local-bus
implementations require different signal connections, the local bus signal VLRDYI
can be connected to either VGARDY (from the local bus device) or to VLRDYO
(from the ÉlanSC310) using switches 2 and 3 on SW3 (switches 1 and 4 are no
connects). Note that VLRDYI corresponds to LRDY on the ÉlanSC310
microcontroller, and VLRDYO corresponds to CPURDY.
evalbd.book : ch2 Page 19 Thursday, August 8, 1996 2:34 PM
DRAM Main Memory
The ÉlanSC310 microcontroller evaluation board comes standard with 2 Mbyte of
standard 30-pin, 70-ns DRAM SIMMs installed on the board. The evaluation board
requires DRAMs with access times of 70 ns or less (for 33 MHz operation). The
DRAM memory can be upgraded using 30-pin SIMMs with 4- or 8-bit DRAMs;
SIMMs with 1-bit DRAMs cannot be used on the evaluation board due to loading
restrictions associated with 32 loads.

SIMM module. This can be installed in the 72-pin SIMM socket located next to
main memory bank 1 on the evaluation board (see Figure 2-1 on page 2-2). On the
72-pin SIMM socket, only 16-bit SIMM modules are fully supported. 32-bit
SIMMs can be used in the 72-pin SIMM socket but only half of the memory will
be visible.
BIOS automatically detects the amount of DRAM installed.
Memory Voltage Setting
The ÉlanSC310 microcontroller evaluation board allows system memory to
operate at either 5 V or 3.3 V. When operating in Local Bus mode, 3.3 V memory
must be used. In order to operate memory at 3.3 V, ensure that the memory is rated
for 3.3-V operation. SW4-1 controls the voltage for the system memory.

I/O
The ÉlanSC310 microcontroller integrates several standard I/O interfaces. A
16C450-compatible UART, bidirectional parallel port is controlled by the
ÉlanSC310 microcontroller. In addition, the ÉlanSC310 microcontroller
evaluation board contains a Super I/O, which contains a 16C550 UART, a floppy
disk controller, and IDE hard drive interface.
A standard 9-pin connector is provided for an extended PC keyboard. A PS/2 port
is provided for use with a PS/2 style mouse. Both the keyboard and PS/2 mouse
are driven by the 8042.
PS/2 Mouse
While in ISA or Local Bus mode, the ÉlanSC310 microcontroller IRQ12 signal is
connected to the IRQ12 signal on the 8042 to control the PS/2 mouse. (See the
settings for JP17 and JP18 in the table below.)

Serial Ports
The evaluation board has two serial ports. Connector P19 is connected to the
ÉlanSC310 internal 16C450-compatible UART. Connector P45 is connected to
the Super I/O 16C550 UART. The BIOS determines how the UART is set up, e.g.,
SystemSoft BIOS allows the ÉlanSC310 to be set up as COM1, COM2, or disabled;
and the Super I/O UART as COM1, COM2, COM3, COM4, or Disabled. (Note
that when the Super I/O UART is configured as COM1 or COM3, the IRQ4 line
from the Super I/O is not connected, therefore polling must be used.)
After DOS is booted, the DOS utility EVALSET.EXE provided on the AMD
Utilities diskette included in your kit can be used to reinitialize either UART to
the desired configuration. Refer to the documentation on the diskette for how to
do this.
Parallel Port
1.0
Connector P20 is connected to the ÉlanSC310 parallel port. Most BIOS’ let you
configure the parallel-port base address in the set-up screen.
IDE Hard Drive
The ÉlanSC310 microcontroller evaluation board contains a standard 40-pin
connection for an IDE drive at location P28 (see the figure on page 2-2). Pin 1 is

Suspend/Resume
The ÉlanSC310 microcontroller evaluation board provides a hardware option to
allow the user to toggle between the High Speed and Suspend modes. By pressing
the Suspend/Resume button after the system has powered up, the system enters the
Suspend mode (assuming the ACIN signal is low). By pressing the Suspend/
Resume button again, the system returns to High Speed mode. The behavior of the
system in Suspend mode depends on the BIOS.
Power Management Simulation
Battery backup conditions can be simulated on the evaluation board by controlling
the ACIN signal to the ÉlanSC310 microcontroller. When ACIN is low, power
management functions on the ÉlanSC310 microcontroller are enabled. When
ACIN is high, power management functions on the ÉlanSC310 microcontroller
are disabled. Switch 8 on SW4 controls the ACIN pin on the ÉlanSC310, allowing
power management functions to take effect if they are enabled.

In order to get true power measurements while in Suspend mode, IRQ1 and PIRQ1
must be disconnected from the ÉlanSC310 microcontroller. The ÉlanSC310
microcontroller drives these signals low during Suspend mode. Since the
peripherals connected to these lines drive them high, this creates the appearance
of additional power drain. These signals can be easily disconnected while in
Suspend mode using switches 2 and 3 on SW4.

1.0
This mode is the lowest power mode for the ÉlanSC310 microcontroller. When
the system is initially powered by turning on the power supply and then pressing
the MicroPower Off button, SW5, the system enters High Speed mode. The red
power light indicates that the system is fully powered on. Pressing the MicroPower
Off button, SW5, again, causes the ÉlanSC310 microcontroller to enter
MicroPower Off mode. During MicroPower Off mode, only AVCC, VCC, and the
32-KHz crystal remain active. The system is essentially off, but the RTC remains
in operation. Please refer to the ÉlanSC310 Microcontroller Data Sheet for a more

The spinning cursor "/" is used to emulate typical CPU activity. This activity gives
a lower current reading for core ÉlanSC310 microcontroller current than if the
processor was sitting idle waiting for keyboard input. This is because cycles to the
ISA devices (which occur as a result of this activity) are run at 9.2 Mhz. CPU idle
cycles occur at the High Speed PLL mode frequency (33/25/20/9.2 Mhz).

"+" or "–" keys on the keyboard. The arrow keys control which item is highlighted.
Matrix items with a "*" after them are fixed in the ÉlanSC310 microcontroller and
cannot be highlighted or changed. Matrix items with a "#" after them are fixed at
the current state due to a requirement of the evaluation board. These items cannot
be highlighted or changed.
Changes made to this screen do not take effect until either the "S" key is pressed

The state of the PMC pins can be set for each PMU mode. While the particular
state the PMC pin is in does not significantly affect the ÉlanSC310
microcontroller’s power consumption, this matrix allows the user to see what
control the user has for external control of the PMC pins for each PMU mode. Note
that the PMC pin setting for the Low and High Speed PLL modes mirror each
other. Changing the value in one column causes the value in the other column to
change also.
High Speed PLL Mode Column
• The CPU speed can be set to 33 Mhz, 25 Mhz, 20 Mhz, or 9.2 Mhz.
• Both the High Speed and Low Speed PLLs for this mode are enabled.
• Auto Low Speed mode, when enabled, switches the CPU clock speed to operate
at 9.2 Mhz for the duration of time listed in ALS Duration matrix item (0.25,
0.50, 1.0, 2.0 seconds). This switch is triggered at a rate determined by the ALS
Trigger matrix item, which can be set to 4, 8, 16, or 32 seconds. The ALS trigger
period and ALS Duration time are stored in write-only registers. Therefore it is
not possible to read the current ÉlanSC310 programed value when this utility
is started. The default values of 4 seconds for the ALS Trigger and 0.25 seconds
for the ALS Duration are programmed at start-up time.
• The CPU Idle Speed can be set to "HIGH" or "LOW." "HIGH" means that during
idle cycles the CPU runs at the current High Speed CPU speed (33, 25, 20, or
9.2 Mhz); "LOW" means 9.2 Mhz. The CPU Idle Speed can only be set "LOW"
if the High Speed CPU is set to 20 Mhz or 9.2 Mhz. If the High Speed CPU
speed is set to 33 Mhz or 25 Mhz and the CPU Idle Speed is then set to "LOW",
the CPU speed changes to 20 Mhz. Similarly, if the CPU Idle Speed is set to
"LOW" and the High Speed CPU speed is changed to 33 Mhz or 25 Mhz, the
CPU Idle speed is changed to "HIGH."

Low Speed PLL Mode Column
• The CPU speed can be set to 4.61 Mhz, 2.30 Mhz, 1.15 Mhz, or 0.58 Mhz.
• The High Speed PLL can be enabled or disabled in this mode.
• The Low Speed PLL is always enabled for this mode.
• The state of the PMC pins for this mode mirror the setting in High Speed PLL
mode. Changing the state in this mode also changes the state for High Speed
PLL mode.
Doze Mode Column
• The CPU for this mode can be turned "OFF," or it can be enabled to run at
9.2 Mhz in response to IRQ0 being generated. "IRQ0-9.2Mhz" appears as the
matrix item. For this mode, the CPU only runs at 9.2 Mhz during the time IRQ0
is being processed. Setting this matrix item to "IRQ0+64 R" enables the CPU
to run at 9.2 Mhz while processing IRQ0 and the CPU remains running for 64
refresh cycles after IRQ0 processing is completed.
• The High Speed PLL is always disabled for this mode.
• The Low Speed PLL and Video PLL (controlled by the same bit) can be enabled
or disabled for this mode.

also an option to enable/disable a transition message. If enabled, a Transition
message is displayed as the ÉlanSC310 microcontroller transitions from Low
Speed to Doze mode, prompting the user to press a key before the system transitions
to Sleep or Suspend mode.

The box on the top right of the screen displays the current state of the BL and ACIN
pins. Status for the BL4 pin is not directly readable by the ÉlanSC310. On the
ÉlanSC310 microcontroller evaluation board, the state of the BL pins and ACIN
pins are controlled by the Red 8 bank DIP switch SW4. Switches 4–7=BL1–BL4;
Switch 8=ACIN.
ACIN must be set to 0 in order for any of the BL pins to cause a PMU state change.
Once a BL pin is used to cause a PMU state change, setting ACIN to 1 (active)
wakes up the system and returns the PMU to High Speed PLL mode.

EvalSet Serial and Parallel Port Setup Utility
EVALSET.EXE has been provided to allow easy activation of the serial and
parallel ports on the ÉlanSC310 microcontroller evaluation board. The BIOS on
this board was designed to be generic, therefore these functions are not enabled by
the BIOS on the evaluation board. This utility can be used to set up the base
addresses for serial port 1, serial port 2 and parallel port 1 on the evaluation board.
Serial Port 1
Serial Port 1 is the 16C450 UART internal to the ÉlanSC310 microcontroller. Its
base address can be set to either 3f8h or 2f8h. The IRQ level can be set to either 3
or 4. If you enter a base address of 0, the internal UART is disabled. If you enter
a valid base address but an IRQ of 0, then the UART is enabled but it is not attached
to an interrupt line.
evalset ser1 0x3f8 4
evalset ser1 0x2f8 3
evalset ser1 0 0
Sets the internal UART to be COM1:
Sets the internal UART to be COM2:
Disables the internal UART
NOTE: Once the base address is set, the UART is programmed to 9600 baud, no
parity, 8 data, 1 stop.
Serial Port 2
Serial Port 2 is connected to the 16C550 UART1 of the Super I/O chip (UART2
is not connected). Its base address can be set according to the table below. Note
that if you want serial port 2 to generate an interrupt, only IRQ3 can be used. This
is because IRQ4 from the Super I/O is not connected. However, the base addresses
that are associated with an IRQ4 configuration can still be set as long as the port
is used in polled mode.

NOTE: Once the base address is set, the UART is programmed to 9600 baud, no

Parallel Port 1
This is the internal parallel port on the ÉlanSC310 microcontroller. The parallel
port base address is controlled through the Bus Configuration Registers (see the
ÉlanSC310 Microcontroller Programmer's Reference Manual). These bus
configuration registers can only be programmed before ISA or Local Bus accesses
are made, so setting the parallel port base address or disabling the parallel port can
only be done at boot time. Thus, the EvalSet utility merely allows control of the
EPP and bidirectional modes on the parallel port. Any base address that is specified
is ignored by the EvalSet utility.

This utility is part of the collateral for the ÉlanSC310 microcontroller. The
ÉlanSC310 microcontroller is a highly integrated device with many subsystems.
Many of these subsystems are unique to the ÉlanSC310. The purpose of the
MMSVIEW utility is to provide the new ÉlanSC310 microcontroller user with
the ability to explore the capabilities of the ÉlanSC310 MMS subsystem without
having to invest much in the way of software development or chip register learning
time.
MMSVIEW is a DOS application that may be used to inspect various resources
that are accessible by the ÉlanSC310 MMS subsystem. These resources include
SYSTEM RAM, the BIOS ROM (or resources accessed by the ROMCS signal),
or the DOS ROM (or resources accessed by the DOSCS signal). With this utility,
the following operations may be performed:
• Directly display any region of the system RAM (0–16 Mbyte range), BIOS ROM
(0–16 Mbyte range), and DOS ROM (0–16 Mbyte range).
• Step forward or backward through the data in 256-byte steps or 16-Kbyte steps.
• Select any ÉlanSC310 MMS page from MMSA to view system resources
through.
• Fill areas of system RAM memory with a selected byte.
• Append the currently displayed page of data to a log file in either ASCII or
binary formats.
• View DOS ROM using an 8- or 16-bit interface.
• Perform continuous read/compare operations from a selected resource, and
indicate miscompares on the display.

Description
evalbd.book : ch3 Page 13 Thursday, August 8, 1996 2:34 PM
Scope
MMSVIEW is provided to enable discovery and understanding of the capabilities
of the ÉlanSC310 microcontroller MMS system. It has other uses such as looking
at DOS ROM disks to ensure that the odd/even parts are placed in the sockets
correctly. It is not designed to be a comprehensive or automated diagnostic
program, although its use may help in the debug of certain problems.
MMSVIEW uses MMSA only. To retain compatibility with systems using VGA
video, MMSB was left outside the scope of this tool. It was designed on, tested on,
and meant for use on the ÉlanSC310 microcontroller evaluation board revision 2.2
or later. The fact that it may run on other customer platforms is purely coincidental
NOTE: No support of any kind is provided for porting this utility to any platform
other than the ÉlanSC310 microcontroller evaluation board revision 2.2 or later
except by special agreement between AMD and the customer.

Operating Instructions
Command-Line Parameters
MMSVIEW assumes that MMS page 4 (resides at D0000h when MMS page 0 is
set up to reside at C0000h) is available for use. This default may be overridden
using a command-line parameter as shown below.
Syntax: MMSVIEW [page]
where:
page is a number from 0–7 to indicate the initial MMS page to view the system
resources through.
If an invalid command-line parameter is detected (not a number, out of range, etc.)
the default MMS page (4) is used. This option is provided to allow resolution of
system address space conflicts that may occur when using this program while some
other driver is loaded (EMM386, etc.).
There are no other command-line parameters available.

Initial State
After MMSVIEW has been invoked from the DOS command line, data is
displayed in a fashion similar to DOS debug. MMSA page 4 at D0000h is selected,
and the device that is accessed is system RAM. The first 256 bytes of the selected
device are displayed starting at offset 0 (i.e., the start of the interrupt vector table
at 0:0 in RAM.)
Keystroke Commands
Keystroke commands are invoked by simply pressing the keys noted below.
Whenever a keystroke command requires user input, prompts request the required
data. If a command that requires user input is to be aborted without invoking the
command, press the Escape key, and the main data display returns. A command
summary follows.
+
The plus key moves forward through the data 256 bytes at a time. The plus key
thus makes it simple to view the next 100h bytes of data on the selected device.
–
The minus key performs the inverse operation of the plus key, and causes the
previous 256 bytes of device data to be displayed. The program disallows negative
addresses, and gives a warning click from the speaker if you press the minus key
when the first address displayed on the screen is 0.
Home Key
The Home key displays the data at offset 0 on the current device.
Escape
The Escape key causes the utility to return control to the DOS prompt. Note that
no cleanup is done as the program exits, so it is recommended that the user COLD
BOOT before performing any other important operations, especially if ROMDOS
or EMM386 drivers were loaded on the system when MMSVIEW was invoked.

?
Pressing the question-mark key from the main data-display screen displays a quick
help list of the keystroke commands available to the utility. Press the Space Bar
from the quick help screen to return to the normal main display screen.
evalbd.book : ch3 Page 15 Thursday, August 8, 1996 2:34 PM
Page Up
The Page Up key displays data on the previous 16-Kbyte boundary. For example,
if the current device data starting at offset 4100h is being displayed, and Page Up
is pressed, the data from device offset 0100h is displayed.
Page Down
The Page Down key does the inverse of the Page Up key; it displays data from the
next 16-Kbyte boundary.
Space Bar
The Space Bar (or any key besides the other command keys listed in this section)
simply rereads the data from the selected resource, and refreshes the main data
display screen. The main data screen does not constantly update normally. Press
the Space Bar (or any other non-command key as specified in this list) to refresh
the screen with the new data. For a continuous read mode, see the c command
below.
a
This key is only useful on boards with PCMCIA.
1.0
c
The c key is useful for detecting changes in reading the data from a given resource.
An example application for this feature is in the detection of timing problems
(incorrect wait-state setup, etc.). When you press the c key, a “snapshot” of the
current device data is taken, and stored into a local buffer. After this, continuous
reads of the current device data are compared to the buffer. Miscompares cause
the offending byte location to Flash, and the result of an Exclusive OR between
the buffer (snapshot) and the current device data is displayed. This allows bit errors
to be picked out easily.
Upon leaving Continuous Read/Compare mode, the blink attribute is removed from
the characters for easier reading of the resulting data. The bytes which have the bit
miscompares are left highlighted in white (versus light gray for the normal data).
Any new command which causes the data to be read from the device again removes
the highlight attribute from the displayed data completely. If the highlight attribute
needs to be removed without losing the bit error data which may have been
captured, the r command may be used (see below).

evalbd.book : ch3 Page 16 Thursday, August 8, 1996 2:34 PM
d
The d key selects which device the current MMS page points to. Pressing the d
key causes the system to prompt for the new device. Enter a 0, 1, or 3 (0 = DOS
ROM, 1 = system RAM, 3 = BIOS ROM), and press enter. Invalid input is not
accepted. Once a new device has been entered, the main data display returns
showing the data read from the selected device at the current offset. For example,
if you are looking at the DOS ROM at offset 4000h, and you use the d command
to select the BIOS ROM, the data displayed is from offset 4000h of the BIOS ROM.
g
The g command allows you to “go” to any place in the memory map desired. It is
the random access equivalent to the plus and minus keys. It provides one additional
benefit in that the data byte which resides at the address specified by the user to
go to is highlighted for easy recognition.
i
The i key allows the DOS ROM interface to be toggled between the 8- and 16-bit
interfaces supported on the ÉlanSC310 microcontroller. This is useful if running
the utility on a hardware platform that has an 8-bit DOS ROM interface as opposed
to the 16-bit DOS ROM interface on the ÉlanSC310 Microcontroller Evaluation
Board.
l
The l command allows one screen’s worth of data to be appended to a log.
Successive screens can be captured to the same file in this manner. Pressing the l
command prompts the user as to whether the output file should be a binary image
of the data, or whether a DOS debug-like ASCII representation should be saved.
If the binary option is chosen, data is logged to a file named MMSVIEW.BIN. If
the ASCII option is selected, the output file is MMSVIEW.ASC.

f
The f command allows a range of memory to be filled with a user-selectable byte.
Pressing the f command brings up prompts for the start and stop fill addresses, and
requests the fill byte. Fill operations are available only when RAM is the selected
device. This command does not know how to write to Flash devices in a DOS ROM
socket.
evalbd.book : ch3 Page 17 Thursday, August 8, 1996 2:34 PM
n
The n command allows the user to select the use of a new MMS page (0–7). This
can be useful in avoiding system conflicts. The default page can be changed before
entering the program using the command-line capability to set this option as
described on page 3-13.
p
The p command is essentially a g command that accepts its input in terms of 16K
pages. In other words, you can randomly access data on specific 16-Kbyte
boundaries using this command. For example, if you want to view the start of the
first 16-Kbyte boundary of a device, select the p command, and input 0 when
prompted to specify page 0. This can be done just as easily using the g command
and supplying an address that’s a multiple of 4000h.
r
The r command resets the miscompare indicators as explained earlier in the section
that explains the c command. See the c command on page 3-15 for more detail.
s
This key is only useful on boards with PCMCIA.

Restrictions on Use
Although designed for the ÉlanSC310 microcontroller evaluation board, this utility
may work on other vendor’s platforms. (However, its functionality outside of the
ÉlanSC310 microcontroller evaluation board cannot be guaranteed and therefore
is not supported.) There are two key elements for compatibility:
1. MMSVIEW assumes that MMSA is programmed to begin page 0 at C0000h.
The starting location of MMSA is not reset by the utility in an attempt to
maintain software compatibility with customer platforms as this would
probably cause the customer’s platform to crash. Use this utility on a customer
platform only if customer-platform initialization programs MMSA page 0 to
start at C0000h.
ÉlanSC310 Microcontroller Evaluation Board User’s Manual
3-17
evalbd.book : ch3 Page 18 Thursday, August 8, 1996 2:34 PM
2. The second element of compatibility is the use of the MMS windows on the
customer platform. MMSVIEW assumes that MMS page 4 (resides at D0000h
when MMS page 0 is set up to reside at C0000h) is available for use. This may
conflict with drivers loaded on the evaluation board platform that require the
use of MMS (ROMDOS, EMM386, etc.). It may also conflict with customer
resources located on customer platforms. See “Operating Instructions” on page
3-13 for details on how to change MMS windows.
Use caution when selecting the MMS page to use. Selecting a page that causes
conflicts with other system resources can lock the system. For example, using a
VGA card in the ISA slot of the evaluation board, and selecting pages 0 or 1 of
MMSA causes system conflicts since VGA BIOS decodes at C0000h for 32 Kbyte,
and MMSA pages 0 and 1 also use that address space.
3-18
ÉlanSC310 Microcontroller Evaluation Board User’s Manual
1.0
It is recommended that the test platform/evaluation system be “cold” booted (using
reset button) after MMSVIEW exits so that the ÉlanSC310 microcontroller setup
registers are restored to the proper values before doing further work on the platform.
This is required not only on customer platforms, but on any ÉlanSC310
microcontroller evaluation board that has any ROMDOS, EMM386, or other
drivers installed that require use of the MMS, or memory regions that are controlled
by the MMS. Again, MMSVIEW makes no attempt to restore the system to its
initial state: reset the system when finished.
evalbd.book : ch3 Page 19 Thursday, August 8, 1996 2:34 PM
Register Dump Utility
This register dump utility has been provided for use on the ÉlanSC310
microcontroller evaluation board. It is intended to provide an easy-to-use registermanipulation program. This program displays the index registers in the ÉlanSC310
microcontroller, grouped by functionality:
• ÉlanSC310 PMU Registers Screen 1
• ÉlanSC310 PMU Registers Screen 2
• ÉlanSC310 MMU/ISA Registers
These registers can be read or written by simply entering a new value and pressing
Return. Some registers do not allow full read/write access. Read-only registers
display the contents of the register but do not allow the user to write a new value.
Write-only registers allow a user to write a new value to the register. When a value
is read from the register, it displays meaningless values. The following is a list of
commands available in REGDUMP.EXE:
Arrow Keys Move the cursor from register to register within the screen.
1.0
s
Toggles between the register screens.
v
Allows user to enter a new value for the selected register.
b
Switches the display to a bit-by-bit definition of the selected register.
m
Switches the display to an options menu screen.
p
Dumps all four register screens to an ASCII text file called
REGDUMP.LOG.
q
Exits from REGDUMP.EXE.
The register value display is read from the registers each time the screen is toggled.
Since the display is not updated with each write, it is possible that a register could
appear to be written to, but if it is a read-only register it remains unchanged. Please
refer to the ÉlanSC310 Microcontroller Programmer’s Reference Manual to
determine if the register being manipulated has any read/write restrictions.
NOTE: This regdump utility is used for both the ÉlanSC300 and ÉlanSC310
microcontrollers. However, some registers or some bits within registers are used
only on the ÉlanSC300. These registers or bits are marked with an "ÉlanSC300
only" indicator on the regdump screens.

Programmable General Purpose (PGP) Pins
The ÉlanSC310 microcontroller has four Programmable General Purpose (PGP)
pins which can be set up as inputs, outputs, address decodes, and address decodes
that are gated with the I/O read or I/O write pulse. Index registers for the PGP pins
are write only. Keep this in mind when writing to Index 91h, which controls all
PGP pins.
Remember, this particular implementation of the PGP pins is specific to the
ÉlanSC310 microcontroller evaluation board only. Other system designs may
implement these pins differently.
The ÉlanSC310 microcontroller evaluation board makes use of the PGP pins as
follows.
This pin in used to clock data from the data bus into a flip-flop that is used to control
the programming voltage to the ROM sockets. PGP0 must be set up to gate with
the I/O Write Command. This is done by setting the ÉlanSC310 Index 91h to
xxxxxx10b. Index 89h is used to set up the I/O address for PGP0. Setting Index
89h to a 20h programs PGP0 to respond to writes to I/O addresses 100h–107h.
PGP0 must also be enabled as an output. This is done by writing bit 6 of the
ÉlanSC310 Index 70h to a 1. By programming this pin as just described, the
ÉlanSC310 microcontroller is now able to write to the 1 bit register at I/O port
100h. When set up as described, the write-only register at I/O address 100 is as
shown in the table below.
NOTE: This pin is referenced as PGPA on the evaluation board schematics
beginning in “Schematics” on page D-1.

PGP1
This pin is used as an address decode for the IDE CS0. It should be programmed
as an address decode for I/O addresses 1F0H–1F7H. Setting the ÉlanSC310
microcontroller’s Index 91h to xxxx11xxb programs PGP1 as an address decode.
Setting ÉlanSC310 Index 9Ch to 3Eh sets the address range to 1F0h–1F7h. PGP1
must also be enabled as an output for the evaluation board. This is done by setting
Bit 2 of the ÉlanSC310 Index 74h.
NOTE: This pin is referenced as PGPB on the evaluation board schematics
beginning in “Schematics” on page D-1.
PGP2
This pin is used as an address decode for the IDE CS1. It should be programmed
as an address decode for I/O addresses 3F0h–3F7h. Setting the ÉlanSC310 Index
91h to xx11xxxxb programs PGP2 as an address decode. Setting the ÉlanSC310
Index 94h to 7Eh sets the address range to 3F0h–3F7h.

Power Management Control (PMC) Pins
The ÉlanSC310 microcontroller has five Power Management Control (PMC) pins
that can be programmed high or low based on the current power management mode.
The ÉlanSC310 microcontroller evaluation board makes use of the PMC pins as
follows.
ÉlanSC310 Microcontroller Evaluation Board User’s Manual
4-3
evalbd.book : ch4 Page 4 Thursday, August 8, 1996 2:34 PM
PMC0
This pin is logically ORed with the system Reset pin from the ÉlanSC310
microcontroller (RSTDRV) and fed to the reset pin of the 8042 keyboard controller.
It is used to perform a software reset to the 8042. A value of 1 drives the reset pin
of the 8042 active. A value of 0 allows for normal operation. The ÉlanSC310
microcontroller Index ACh bits 3:0 control PMC0 and are set to 0 on power-up.
If you are not using PMU states that turn off the Low Speed PLL (i.e., Doze, Sleep
or Suspend modes) then you do not need to change the settings for this pin. Refer
to “8042 Keyboard Controller” on page 4-14 for a further explanation of when you
need to do a software reset.
PMC1
This pin is not used on this board.
This pin is used to select whether the internal ÉlanSC310 microcontroller (serial
port 1) and the Super I/O (serial port 2) are enabled for RS232 serial data
(PMC2=1), or whether the IR Transmitter/Receiver pair is used to send and receive
serial data on serial port 1, and serial port 2 transmission is disabled (PMC2=0).
The ÉlanSC310 Indexes 80h and 81h control the state of PMC2.
PMC3
This pin is not used on this board.
PMC4
This pin is used to mask the system reset pin from the 8042 keyboard controller
that is fed to the Reset CPU pin (RC) of the ÉlanSC310 microcontroller. A value
of 1 holds the CPU’s RC input High, and prevents the 8042 keyboard controller’s
reset output from reaching the CPU. A value of 0 allows for normal operation. The
ÉlanSC310 Index ACh bits 3:0 control this pin and are set to 0 on power-up. If
you are not using PMU states Doze, Sleep, Suspend or Off, then you do not need
to change the settings for this pin.

Programming BIOS Flash/EPROM
or Application Flash/EPROM
This section describes how to program a Flash or EPROM device located in the
BIOS sockets (U20 or U59), and the application sockets (U16, U17, U18, U19).
The following items need to be addressed:
• Controlling the programming voltage for 12-V parts such as the AMD 28F020A
• Enabling writes to the BIOS and application ROM sockets
• Address mapping of the Flash sockets
• Evaluation board jumper settings
Controlling VPP
1.0
There is one control for the VPP line for all BIOS and application ROM
sockets (i.e., there is no way to individually control the VPP line for each socket).
As described in the section “Programmable General Purpose (PGP) Pins” on page
4-2, PGP0 is used to clock the flip flop that controls the programming voltage to
the ROM sockets. When Data Bit 2 is set to 1, VPP is set to 12 V for all ROM
sockets. See “Initialization Example for Flash Programming” on page 4-7.
Enabling Writes to the BIOS and Application ROM Sockets
Writes to the BIOS sockets and application sockets need to be specifically enabled
(they are disabled by default). This is accomplished by setting to a 1 bits 6 and 5
of the ÉlanSC310 Index 62h.
NOTE: Accesses to the BIOS socket or application socket are ISA cycles plus the
additional ROMCS or DOSCS signal going active. No special logic has been added
to the evaluation board to stop a ROMCS or DOSCS cycle from going to the ISA
bus. Because of this, if the ÉlanSC310 microcontroller is in Full ISA mode, an ISA
card (such as a VGA card) set up to respond to a memory range interferes with
cycles going to the application or BIOS sockets. For example, a VGA card with
on-board BIOS responds to the address range from A0000h through C7FFFh. An
access to the application ROM socket through the MMS page to an offset in this
range causes both the VGA card and the application ROM to respond. The only
way to avoid this is by either not accessing this range, or reworking the evaluation
board.
ÉlanSC310 Microcontroller Evaluation Board User’s Manual
4-5
evalbd.book : ch4 Page 6 Thursday, August 8, 1996 2:34 PM
Address Mapping of the Flash/EPROM Sockets
The BIOS sockets have an 8-bit interface. Only one socket (U20) or (U59) can be
enabled depending on the setting of jumper JP32. Address lines A0–A17, 256K
addressing, are connected to the socket. The BIOS ROM can be accessed for
programming by either using an MMS page, or setting up a linear decode region
(see the ÉlanSC310 Microcontroller Programmer’s Reference Manual).
Typically, an MMS page is used.
The application sockets have a 16-bit interface. If BIOS does not already enable
the 16-bit interface, this needs to be done after boot-up by setting to a 1 bit 1 of
the ÉlanSC310 Index 51h. Even addresses access sockets U16 and U18. Odd
addresses access sockets U17 and U19. Support for both 256Kx8 Flash or EPROM,
and 512Kx8 EPROM parts exists. Jumper JP13 controls which is selected.
When set for 256Kx8 parts: even addresses from 0–7FFFEh access socket U16;
odd addresses from 1–7FFFFh access socket U17; even addresses from 80000h–
FFFFEh access socket U18; and odd addresses from 80001h–FFFFFh access
socket U19.
When set for 512Kx8 parts: even addresses from 0–FFFFEh access socket U16;
odd addresses from 1–FFFFFh access socket U17; even addresses from 100000h–
1FFFFEh access socket U18; and odd addresses from 100001h–1FFFFFh access
socket U19. The application address space is accessed by using an MMS page or
by enabling the linear decode for the application ROM. Using an MMS page is
recommended because it can be accessed using real mode addressing.
Evaluation Board Jumper Settings
There are three jumpers which affect Flash programming on the ÉlanSC310
microcontroller evaluation board.
4-6
JP32:
This jumper controls whether BIOS socket U20 (JP32=2-3) or socket
U59 (JP32=1-2) is used.
JP12:
This jumper must be set to 1-2 when Flash parts are used (JP12=2-3
indicates EPROM parts).
ÉlanSC310 Microcontroller Evaluation Board User’s Manual

NOTE: 512Kx8 Flash can be supported after a minor board rework. Contact your
local AMD or distributor Field Application Engineer for more information.
evalbd.book : ch4 Page 7 Thursday, August 8, 1996 2:34 PM
JP13:
This jumper must be set to 1-2 to indicate 256Kx8 parts are in the
application sockets. (JP13=2-3 indicates 512Kx8 parts, and 512Kx8
Flash is only supported after a minor board rework. Contact your
local AMD or distributor Field Application Engineer for details.)

2. MMSA pages 0 and 1 are disabled allowing accesses to the address range at
C0000h–C7FFFFh to propagate to the ISA bus where the VGA BIOS is located.
3. Addresses E0000h–FFFFFh are set up as linear decodes to the BIOS ROM
(Index 65h, bit 0=0, bit 1=1, bit 2=0, bit 3=0). During BIOS initialization, if
shadowing is enabled (ÉlanSC310 Index 65h bit 4=1, ÉlanSC310 Index
69h=FFh), then accesses to this address range go to DRAM.
4. Refer to the ÉlanSC310 Microcontroller Programmer’s Reference Manual for
information on ROM BIOS and ROM DOS accesses using the MMS pages.

DOS ROM/Application ROM Mapping
The application ROM space (also known as DOS ROM space) is selected by the
DOSCS chip select. Only 256Kx8 Flash parts are supported; 256Kx8 and
512Kx8 EPROMs are supported. JP12 selects between Flash/EPROM (1-2 = Flash,
2-3 = EPROM). JP13 selects between 256Kx8 and 512Kx8 parts (1-2 = 256K,
2-3 = 512K).
NOTE: 512Kx8 Flash can be supported after a minor board rework. Contact your
local AMD or distributor Field Application Engineer for more information.
Access to the application ROM begins at offset 0h, and extends up to 1FFFFFh,
depending on the size and number of parts installed. Application ROM is accessed
through the MMS windows.
It is also possible to access linear decoded application ROM. This requires setting
up ÉlanSC310 Index B8h. However, the processor must be set up to access memory
above the 1 Mbyte boundary.
BIOS ROM Mapping
1.0
BIOS ROM mapping is similar to application ROM mapping. BIOS ROM is
selected by the BIOSCS chip select. 128Kx8 and 256Kx8 Flash and EPROM
devices are supported.
Access to the BIOS ROM begins at offset 0h, and extends up to 3FFFFh, depending
on the size of the device. Typically the BIOS ROM is accessed through a linear
decode set up for the address range E0000h through FFFFFh. This is set up using
ÉlanSC310 Index register 65h. It is also possible to access the BIOS ROM using
pages in the MMS windows.

Evaluation Board’s Components
8042 Keyboard Controller
The evaluation board uses a non-static 8042 keyboard controller. What this means
to the programmer is that if SysCLK stops being driven to the 8042 for any period
of time, the controller must be reset once SysCLK starts being driven again in order
for the 8042 to function properly. The ÉlanSC310 microcontroller stops driving
SysCLK any time the Low Speed PLL is disabled or when in Sleep, Suspend and
Off PMU modes even if the Low Speed PLL is enabled for these modes. One side
effect of not driving SysCLK to the 8042 is the RC pin from the 8042 will go active
for a short period of time. This active state is latched by the ÉlanSC310
microcontroller. Therefore when the ÉlanSC310 microcontroller goes back to High
Speed PLL mode from Sleep, Suspend or Off mode, the CPU is reset.
To work around these situations, the evaluation board has been wired to use two
pins on the ÉlanSC310 microcontroller to gate RC from the 8042 (PMC4) and to
reset the 8042 (PMC0). PMC4 should be programmed to mask off the RC pin from
the 8042 while in Sleep, Suspend, and Off modes to prevent the CPU from being
reset due to SysCLK not being driven out of the ÉlanSC310. (If the Low Speed
PLL is to be disabled in Doze mode then PMC4 should be driven for this mode as
well.) When the system goes back to High Speed PLL mode, the 8042 needs to be
reset by pulsing PMC0 high for 1 millisecond. Commands should also be issued
to the 8042 to re-enable the keyboard. See “PMC0” on page 4-4 and “PMC4” on
page 4-4 for more information.
National Super I/O PC87322VF
The Super I/O is set up to decode address 398h and 399h for its index and data
registers.
When configuring the serial port on the Super I/O it is important to note that IRQ3
from the chip is connected to PIRQ0 on the ÉlanSC310 microcontroller. (Note:
PIRQ0 on the ÉlanSC310 is internally set to IRQ3 when in Full ISA Bus mode; it
is programmable in all other bus modes.) IRQ4 from the Super I/O is not connected.
Therefore when configuring the serial port in the Super I/O, only configure it to
use IRQ3. Also PMC2 must be set to 1 in order to enable the RS232 drivers for
the serial port.
4-14
ÉlanSC310 Microcontroller Evaluation Board User’s Manual
1.0
Note that the above conditions only apply to a non-static 8042. If a static 8042 is
used, then these conditions don’t apply.
evalbd.book : ch4 Page 15 Thursday, August 8, 1996 2:34 PM
The Super I/O parallel port is not connected and therefore should not be enabled.
The floppy drive interface on the Super I/O is enabled. DMA channel 2 is used
and the floppy IRQ is connected to PIRQ1 on the ÉlanSC310 microcontroller.
(Note: PIRQ1 on the ÉlanSC310 is internally set to IRQ6 when in Full ISA Bus
mode; it is programmable in all other bus modes.)
IDE Interface
An IDE drive can be directly connected to the ÉlanSC310 microcontroller. On the
evaluation board, data bit 7 is routed through the Super I/O in order to properly
handle bit 7 for I/O addresses 3F6 and 3F7, which are jointly used by the Floppy
and the IDE interface. The IRQ line from the IDE connector is connected to IRQ14
on the ÉlanSC310 microcontroller. PGP1 is used for the IDE chip select 1 (I/O
address 1f0–1F7h). PGP2 is used for IDE chip select 2 (I/O address 3f6–3f7). See
“Connecting an IDE Hard Drive” on page 1-7 for the steps to connect the drive.
Enabling the ÉlanSC310 Internal Serial Port
1.0
The ÉlanSC310 microcontroller internal serial port is typically configured as
COM1. The following ÉlanSC310 index registers need to be set for this
configuration:
• Elan Index 77h = 90h ; Enable internal UART to base address 3F8 and IRQ 4
(COM1)
• Elan Index 92h = 01h ; Enable clock to UART
• Elan Index 48h = 02h ; Set for 16C450 compatibility
• Set pin PMC2 active for all PMU modes (refer to “Power Management Control
(PMC) Pins” on page 4-3).
The UART’s I/O registers 3F8h–3FFh can now be accessed to perform serial
transfers.

Board Layout Suggestions
The following suggestions concern the ÉlanSC310 microcontroller evaluation
board layout strategy for the 32-kHz oscillator, the PLLs, and the power supplies.
The goal is to minimize noise and noise coupling associated with the way the board
is laid out. Special care is needed to minimize board leakages which can be fatal
to pins that are sensitive to leakage currents, such as the two crystal oscillator pins,
XTAl1 and XTAL2.
32-kHz Oscillator
Prudent board layout for the 32-kHz oscillator suggests the following precautions:
• Keep the two traces, XTAL1 and XTAL2, as short as possible, especially the
input trace, XTAL1. XTAL1 is extremely sensitive to leakage. Total leakage
from/to XTAL1 to/from all the pins on the board must be kept under 300 nA.
XTAL2 can tolerate a leakage as high as 900 nA.
1.0
• Keep all noisy signals (e.g., PLL outputs and other clocking signals) as far away
from XTAL1 and XTAL2 as possible. Again, XTAL1 is much more sensitive
to noise coupling than XTAL2.
• Minimize parasitic capacitance between XTAL1 and XTAL2; even a few
picofarads can potentially cause the oscillation frequency to be off target.
• Do not use a feedback resistor larger than 20 MΩ; it may fail to start up if the
leakage at XTAL1 is equivalent to 5MΩ or less. The feedback resistor value
can be lowered to counter leakage at XTAL1, but that increases start-up time.
The lower bound for the feedback resistor should be about 10 MΩ.
• The capacitors connected between XTAL1, XTAL2, and analog ground should
be between 15 pF and 30 pF, and they should be about equal in value. Increasing
the two capacitor values increases start-up time and power consumption, but it
does reduce noise coupling into XTAL1 and XTAL2.
ÉlanSC310 Microcontroller Evaluation Board User’s Manual
C-1
evalbd.book : appc Page 2 Thursday, August 8, 1996 2:34 PM
Phase-Locked Loops
Board layout considerations for the four PLLs suggest the following precautions:
• Keep the output traces for the four PLLs as short as possible and keep them as
far away from each other (and other clocking signals) as possible.
• Do not exceed the specified AC loading for the four PLL outputs. Certainly no
DC loading is allowed since they are all CMOS logic outputs. If the PLLs have
to drive more load than they are designed for in the actual application, make
sure they are properly buffered on the board.
Power Supplies
• Bring the analog VCC and digital VCC on separate traces from the output of the
voltage regulator to the ÉlanSC310 microcontroller; making sure the traces are
thick and wide. Filter the analog VCC with an RLC second-order low-pass filter
(e.g., R= 10 Ω, L=47 µH, C=33 µF). Since the digital VCC carries much more
current than the analog VCC, a second order LC low-pass filter should be used
instead (i.e., the series resistor should be removed). A small capacitor in the
order of a few nanofarads can be added in parallel to the large filter capacitor
to suppress high-frequency noise.
• Isolate the analog ground plane from the digital ground plane on the board, and
connect them after decoupling.

Note: (ElanSC300 only)
The 555 Timer is configured to function as a one-shot.
ElanSC300 revs B1 & B2 deliver a short RESDRV pulse
when exiting uPower OFF mode which could cause some issues. That is the reason for this one-shot.
The ElanSC300 rev B3 device will address this issue & the one-shot is not needed.
- ElanSC300 only -
NOTE
Place these componments close to the
ELAN Socket pins to minimize trace length.

Note: (only one resistor can be populated).
If using ElanSC300 rev B or ElanSC310 without the parallel port,
install R236 and depop R237.
* - Note: if using ElanSC310, do not populate R309 and R326 - R339.
If using ElanSC300 rev B or ElanSC310 with the parallel port,
install R237 and depop R236.
If using ElanSC300 rev A, always install R237 and Depop R236.
ElanSC300 Only: Place Resistors R309-R340 as close as possible to ELAN.
Depop Resistors R309-R340 when running internal CGA mode at 33 MHZ to minimize capacitive loading on DRAM signals.
Removing Resistors will disable local bus video connector and SRAM sockets.
