Regulatory Compliance
The ADSP-21479 EZ-Board is designed to be used solely in a laboratory
environment. The board is not intended for use as a consumer end product or as a portion of a consumer end product. The board is an open
system design which does not include a shielded enclosure and therefore
may cause interference to other electrical devices in close proximity. This
board should not be used in or near any medical equipment or RF devices.
The ADSP-21479 EZ-Board is currently being processed for certification
that it complies with the essential requirements of the European EMC
directive 89/336/EEC amended by 93/68/EEC and therefore carries the
“CE” mark.
The EZ-Board evaluation system contains ESD (electrostatic discharge)
sensitive devices. Electrostatic charges readily accumulate on the human
body and equipment and can discharge without detection. Permanent damage may occur on devices subjected to high-energy discharges. Proper ESD
precautions are recommended to avoid performance degradation or loss of
functionality. Store unused EZ-Boards in the protective shipping package.

PREFACE
Thank you for purchasing the ADSP-21479 EZ-Board™, Analog
Devices, Inc. evaluation system for SHARC® processors.
SHARC processors are based on a 32-bit super Harvard architecture that
includes a unique memory architecture comprised of two large on-chip,
dual-ported SRAM blocks coupled with a sophisticated IO processor,
which gives a SHARC processor the bandwidth for sustained high-speed
computations. SHARC processors represents today’s de facto standard for
floating-point processing, targeted toward premium audio applications.
The evaluation board is designed to be used in conjunction with the VisualDSP++® development environment to test the capabilities of the
ADSP-21479 SHARC processors. The VisualDSP++ development environment aids advanced application code development and debug, such as:
• Create, compile, assemble, and link application programs written
in C++, C, and assembly
• Load, run, step, halt, and set breakpoints in application programs
• Read and write data and program memory
• Read and write core and peripheral registers
• Plot memory
Access to the processor from a personal computer (PC) is achieved
through a USB port or an external JTAG emulator. The USB interface of
the standalone debug agent gives unrestricted access to the processor and
evaluation board’s peripherals. Analog Devices JTAG emulators offer

Default Configuration
The EZ-Board evaluation system contains ESD (electrostatic discharge) sensitive devices. Electrostatic charges readily accumulate on the human body
and equipment and can discharge without detection. Permanent damage may
occur on devices subjected to high-energy discharges. Proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Store unused EZ-Boards in the protective shipping package.
The ADSP-21479 EZ-Board board is designed to run outside your personal computer as a stand-alone unit. You do not have to open your
computer case.
When removing the EZ-Board from the package, handle the board carefully to avoid the discharge of static electricity, which can damage some
components. Figure 1-1 shows the default jumper and switch settings,

Using ADSP-21479 EZ-Board
EZ-Board Installation
For correct operation, install the software in the order presented in the
VisualDSP++ Installation Quick Reference Card. Substitute instructions in
step 3 with instructions in this section.
There are two options to connect the EZ-Board hardware to a personal
computer (PC) running VisualDSP++ 5.0: via an Analog Devices emulator or via a standalone debug agent module. The standalone debug agent
allows a debug agent to interface to the ADSP-21479 EZ-Board. The
standalone debug agent is shipped with the kit.
To connect the EZ-Board to a PC via an emulator:
1. Plug the 5V adaptor into connector P5 (labeled 5.0V).
2. Attach the emulator header to connector P1 (labeled JTAG) on the
back side of the EZ-Board.
To connect the EZ-Board to a PC via a standalone debug agent:
The debug agent can be used only when power is supplied from the
a wall
adaptor.
1. Attach the standalone debug agent to connectors P1 (labeled JTAG)
and ZP1 on the backside of the EZ-Board, watching for the keying
pin of P1 to connect correctly.
2. Plug the 5V adaptor into connector P5 (labeled 5.0V).
3. Plug one side of the provided USB cable into a USB connector of
the standalone debug agent. Plug the other side of the cable into
a USB port of the PC running VisualDSP++ 5.0 update 8 or later.
4. Verify that the yellow USB monitor LED on the standalone debug
agent (LED4, located on the back side of the board) is lit. This signifies that the board is communicating properly with the host PC
and ready to run VisualDSP++.

SDRAM Interface
SDRAM Interface
The ADSP-21479 processor connects to a 32 MB Micron
MT48LC16M16A2P-6A chip through the SDRAM controller. The
SDRAM memory controller on the processor and SDRAM memory chip
are powered by the on-board 3.3V regulator. The SDRAM controller and
memory on the EZ-Board can operate at a maximum clock frequency of
133 MHz.
With a VisualDSP++ session running and connected to the EZ-Board via
the USB standalone debug agent, the SDRAM registers are configured
automatically each time the processor is reset. The values are used whenever SDRAM is accessed through the debugger (for example, when
viewing memory windows or loading a program).
To disable the automatic setting of SDRAM registers, select Target
Options from the Settings menu in VisualDSP++ and uncheck Use XML
reset values. For more information on changing reset values, refer to the
online Help.
An example program is included in the EZ-Board installation directory to
demonstrate how to setup and access the SDRAM interface. For more
information on how to initialize the registers after a reset, search the VisualDSP++ online Help for “reset values”.
SRAM Interface
The board has a 1M x 16-bit flash memory connected to the processor’s
asynchronous memory interface (AMI). The SRAM can be accessed via
the asynchronous memory select 3 pin. It allows access to 16 bits of data
and interfaces to address line 0 through 19 of the processor.
An example program is included in the EZ-Board installation directory to
demonstrate how to setup and access the SRAM interface. For more infor-

mation on how to initialize the registers after a reset, search the
VisualDSP++ online Help for “reset values”.
Parallel Flash Memory Interface
The parallel flash memory interface of the ADSP-21479 EZ-Board contains a 4 MB (4M x 8 bits) Numonyx M29W320EB chip. Flash memory
is connected to the 8-bit data bus and address lines 0 through 21. Chip
enable is decoded by the MS1 select line (default) through switch SW13
position 2. See “External Port Enable Switch (SW13)” on page 2-12. The
address range for flash memory is 0x0400 0000 to 0x043F FFFF.
Flash memory is pre-loaded with boot code for the power-on-self test
(POST) program. For more information, refer to “Power-On-Self Test”
on page 1-22.
By default, the EZ-Board boots from the 8-bit parallel flash memory. The
processor boots from flash memory if the boot mode select switch (SW4) is
set to position 2; see “Boot Mode Select Switch (SW4)” on page 2-10.
Flash memory code can be modified. For instructions, refer to the online
Help and example program included in the EZ-Board installation
directory.
For more information about the parallel flash device, refer to the Numonyx Web site: http://www.numonyx.com.
SPI Interface
The ADSP-21479 processor has two SPI ports, which can be accessed via
the digital peripheral interface (DPI) pins.
ADSP-21479 EZ-Board Evaluation System Manual
1-11
Watch Dog Timer Interface
The SPI flash memory, a 16 Mb ST M25P16 device, connects to the SPI
port of the processor and designates:
• DPI pin 5 (DPI_P5) as a chip select
• DPI pin 3 (DPI_P3) as the SPI clock
• DPI pin 1 (DPI_P1) as the master out slave in (MOSI) pin
• DPI pin 2 (DPI_P2) as the master in slave out (MISO) pin
The same SPI port and DPI pins are connected to the serial flash memory
and audio codec via switch SW3. See “DPI [1–8] Enable Switch (SW3)” on
page 2-9. The DPI pins also are available on the expansion interface II.
By default, the EZ-Board boots from the 8-bit flash parallel memory. SPI
flash can be selected as the boot source by setting the boot mode select
switch (SW4) to position 1. See “Boot Mode Select Switch (SW4)” on
page 2-10.
The audio codec is set up to use DPI pin 4 as the SPI chip select. For more
information, refer to “Audio Interface” on page 1-15.
Watch Dog Timer Interface
The ADSP-21479 processor includes a 32-bit watch dog timer (WDT)
that can be used to implement a software watch dog function. A software
watch dog can improve system reliability by forcing the processor to a
known state through generation of a system reset if the timer expires
before being reloaded by software. Software initializes the count value of
the timer and then enables the timer.
The watch dog timer resets both the core and internal peripherals. After
an external reset, the WDT must be disabled by default. Software must be
able to determine if the watch dog has been the source of the hardware
reset by interrogating a status bit in the watch dog timer control register.
1-12
ADSP-21479 EZ-Board Evaluation System Manual
Using ADSP-21479 EZ-Board
Be default, the watch timer interface is turned off. In order to use the feature, a user needs to turn switch SW13 position 8 ON. SW13 connects the
watch dog reset out pin to the ADM708 system reset circuit. See “External
Port Enable Switch (SW13)” on page 2-12. Special attention must be paid
to this function because it can cause the processor and EZ-Board to
remain in a permanent reset.
Example programs are included in the EZ-Board installation directory to
demonstrate watch dog timer functionality.
Real-Time Clock Interface
The real-time clock (RTC) of the ADSP-21479 processor provides a
robust set of digital watch features, including current time, stopwatch, and
alarm. The RTC is clocked by a 32.768 kHz crystal external to the processor. The RTC peripheral has dedicated power supply pins so that it can
remain powered up and clocked even when the rest of the processor is in a
low power state. The RTC provides several programmable interrupt
options, including interrupt per second, minute, hour, or day clock ticks,
interrupt on programmable stopwatch countdown, or interrupt at a programmed alarm time. An RTCLKOUT signal that operates at 1 Hz is also
provided for calibration.
The 32.768 kHz input clock frequency is divided down to a 1 Hz signal
by a prescaler. The counter function of the timer consists of four counters:
a 60-second counter, a 60-minute counter, a 24-hour counter, and an
32,768-day counter. When the alarm interrupt is enabled, the alarm function generates an interrupt when the output of the timer matches the
programmed value in the alarm control register. There are two alarms:
The first alarm is for a time of day. The second alarm is for a day and time
of that day.
The stopwatch function counts down from a programmed value, with
one-second resolution. When the stopwatch interrupt is enabled and the
counter underflows, an interrupt is generated.
ADSP-21479 EZ-Board Evaluation System Manual

Shift Register Interface
Example programs are included in the EZ-Board installation directory to
demonstrate RTC functionality.
Shift Register Interface
The shift register (SR) of the ADSP-21479 processor can be used as a
serial to parallel data converter. The shift register module consists of an
18-stage serial shift register, 18-bit latch, and three-state output buffers.
The shift register and latch have separate clocks. Data is shifted into the
serial shift register on the positive-going transitions of the shift register
serial clock (SR_SCLK) input. The data in each flip-flop is transferred to the
respective latch on a positive-going transition of the shift register latch
clock (SR_LAT) input.
The shift register’s signals can be configured as follows.
• The SR_SCLK can come from any of the SPORT0–7 SCLK outputs,
PCGA/B clock, any of the DAI pins (1–8), and one dedicated pin
(SR_SCLK).
• The SR_LAT can come from any of SPORT0–7 frame sync outputs,
PCGA/B frame sync, any of the DAI pins (1–8), and one dedicated
pin (SR_LAT).
• The SR_SDI input can from any of SPORT0–7 serial data outputs,
any of the DAI pins (1–8), and one dedicated pin (SR_SDI).
Note that the SR_SCLK, SR_LAT, and SR_SDI inputs must come from the
same source, except in case of where SR_SCLK comes from PCGA/B or
SR_SCLK and SR_LAT come from PCGA/B.
If SR_SCLK comes from PCGA/B, then SPORT0–7 generate SR_LAT and
SR_SDI signals. If SR_SCLK and SR_LAT come from PCGA/B, then SPORT0–7
generate SR_SDI signal.
1-14
ADSP-21479 EZ-Board Evaluation System Manual
Using ADSP-21479 EZ-Board
Access to the shift register of the processor is available via the shift register
interface connector (P4). Users can use a standard 2 mm ribbon cable if
they require off-board capabilities. For more information, see “Shift Register Interface Connector (P4)” on page 2-27.
S/PDIF Interface
The ADSP-21479 processor has a built-in S/PDIF transmitter and
receiver for digital audio applications. The EZ-Board supports the S/PDIF
interface and brings out both the transmitter and receiver via RCA connectors J6 and J7, respectively. The S/PDIF’s in and out pins are
connected by DAI pins via switches SW1 and SW7:
• DAI pin 1 (DAI_P1) as SPDIF_OUT
• DAI pin 18 (DPI_P18) as SPDIF_IN
and SW7 can be turned OFF to disconnect the DAI pins from the RCA
connectors if the pins are used on the expansion II interface. See “DAI [1–
8] Enable Switch (SW1)” on page 2-8 and “DAI [17–20] Enable Switch
(SW7)” on page 2-11 for more information.
SW1
Audio Interface
The AD1939 device is a high-performance, single-chip codec featuring
eight digital-to-analog converters (DACs) for audio output and four analog-to-digital converters (ADCs) for audio input. This translates to four
stereo channels of audio out and two stereo channels of audio in.
The codec can input and output data at a sample rate of up to 192 kHz on
all channels.
The analog audio channels are available via single-ended RCA connectors
(J4 and J5) or differential DB25 connectors (P8 and P9). By default, the
EZ-Board is shipped with the RCA connectors used by the AD1939 codec
ADSP-21479 EZ-Board Evaluation System Manual
1-15
Audio Interface
for audio in and out. To use the differential connectors, change DIP
switches SW15–18. A standard, off the shelf DB25 connector to XLR cables
is required to operate in this mode.
For more information, see “Audio In1 Left Selection Switch (SW15)” on
page 2-14 through “Audio In2 Left Selection Switch (SW18)” on
page 2-16, and “ADSP-21479 EZ-Board Schematic” on page B-1.
The processor interfaces with the codec via DAI and DPI pins. The DAI
pins can be configured to transfer serial data from the codec in Time-Division Multiplexing (TDM) or Integrated Interchip Sound (I2S) mode. See
“DAI Interface” on page 2-3 for more information about the AD1939
connection to the DAI. The DPI interface pins can be configured to use
the SPI interface of the processor to set up the codec’s control registers.
See “DPI Interface” on page 2-4 for more information about the AD1939
connection to the DPI.
The master input clock (MCLK) of the codec is generated by the on-board
12.288 MHz oscillator. The internal PLL of the codec is used to generate
varying sample rates. The codec can be set up for 48 KHz, 96 KHz, or
192 KHz frequencies. The codec can run at these frequencies in both
TDM and I2S modes with all ADCs inputs and DACs outputs. To run
192 KHz with all ADCs and DACs in TDM mode, the codec must run in
dual-line TDM mode.
For information on how to configure the multi-channel codec, refer to the
product datasheet at:
http://www.analog.com/en/audiovideo-products/audio-codecs/ad1939/products/product.html.
The EZ-Board is connected to the AD1939 codec in master mode. The
internal PLL drives the ABCLK and ALRCLK clock signals out. Both clocks
are driven back to the codec’s DBCLK and DLRCLK pins via the R257 and R258
resistors. The ABCLK and ALRCLK clocks that are driven by the codec also
connect to the processor’s serial ports via the DAI pins. Resistors R262 and
R263 are used to feed the bit clock and frame sync signals of the processor’s
1-16
ADSP-21479 EZ-Board Evaluation System Manual
Using ADSP-21479 EZ-Board
serial ports. Connecting the codec in this manner enables a flexible audio
sample rate and allows the processor to run at the maximum core
frequency.
The audio interface also has a 3.5 mm connector (J8) for headphones. The
headphones share the output with the external DAC5 and DAC6 circuits of
the analog audio interface. Switch SW23 must be enabled for the headphones. A volume control potentiometer (R493) is used to increase or
decrease the headphone’s volume. For more information, see “Headphone
Enable Switch (SW23)” on page 2-18.
Example programs are included in the EZ-Board installation directory to
demonstrate how to configure and use the board’s analog audio interface.
The DAI and DPI pins going to the AD1939 device can be disabled, then
used again on the expansion II interface. Refer to “DAI Interface” on
page 2-3 and “DPI Interface” on page 2-4 for more information about the
DAI and DPI switches.
UART Interface
The ADSP-21479 processor features a built-in universal asynchronous
receiver and transmitter (UART). The UART interface supports full
RS-232 functionality via the Analog Devices 3.3V ADM3202 line driver
and receiver (U8). The UART signals are available on the EZ-Board via a
DIP switch (SW14). The UART signals routed through the DIP switch can
be disconnected from the respective DPI interface and used on the expansion II interface. The following DPI pins are used for the RS-232
interface.
• DPI pin 9 (DPI_P9) as UART_TX
• DPI pin 10 (DPI_P10) as UART_RX
ADSP-21479 EZ-Board Evaluation System Manual

LEDs and Push Buttons
• DPI pin 11 (DPI_P11) as UART_RTS
• DPI pin 12 (DPI_P12) as UART_CTS
Example programs are included in the EZ-Board installation directory to
demonstrate UART and RS-232 operations.
For more information about the UART interface, refer to the
ADSP-214xx SHARC Processor Hardware Reference.
LEDs and Push Buttons
The EZ-Board has eight general-purpose user LEDs connected directly to
the processor, one EZ-Board power LED, and one board reset LED. The
EZ-board also has five push buttons: four general-purpose push buttons
connected directly to the processor and one push button for a board reset.
Table 1-3 summarizes LED connections to the processor. To use the
LEDs connected to DAI or DPI, configure the respective registers of the
processor. For more information, refer to the ADSP-214xx SHARC Processor Hardware Reference.

Using ADSP-21479 EZ-Board
Two general-purpose push buttons are attached to the flag pins of the processor, while the other two are attached to the DAI pins. All of the push
buttons and LEDs are connected to the processor through DIP switches.
The DIP switches can disconnect the processor pins, which in turn are
connected to the push buttons and LEDs. See the respective switch section
in “ADSP-21479 EZ-Board Hardware Reference” on page 2-1.
The state of the push buttons connected to the flag pins can be determined by reading the FLAG register. The push buttons connected to the
DAI pins must be configured as interrupts. It is necessary to set up an
interrupt routine to determine each pin’s state. Table 1-3 shows the push

JTAG Interface
The JTAG connector (P1) allows the standalone debug agent module to
connect a VisualDSP++ debug session to the ADSP-21479 processor. The
debug agent operates only when the external 5V wall adaptor (P5) is used.
The standalone debug agent can be replaced by an external emulator, such
as the Analog Devices high-performance USB-based emulator. Be careful
not to damage the connectors when removing the debug agent. The emu-

JTAG Interface
lator is connected to P1 on the back side of the board. See “EZ-Board
Installation” on page 1-5 for more information.
The ADSP-21479 EZ-Board can be set up as a single- or multi-processor
system. By default, the board is set up in single-processor mode. In single-processor mode, create a VisualDSP++ session based on a standalone
debug agent or an external emulator. To use the EZ-Board in multi-processor mode, install an external emulator. Only one external emulator is
required for the main EZ-Board; other EZ-Boards in the JTAG chain do
not require an emulator. In this mode, create a VisualDSP++ platform
based on the number of JTAG devices in the JTAG chain using the VisualDSP++ Configurator. Then create a session in VisualDSP++ based on
the newly created platform.
For a dual ADSP-21479 EZ-Board session, connect two EZ-Boards via
connectors J3 and P10. Flip one of the two EZ-Boards by 180 degrees to
allow the boards to mate. To switch between single- and multi-processor
modes, use DIP switches SW19–22. For more information, see “JTAG
Switches (SW19–22)” on page 2-16.
For three or more ADSP-21479 EZ-Board sessions, connect each of the
EZ-Board with JTAG cables. The cables connect JTAG pins of each
EZ-Board. By using the cables, you put the EZ-Board in a JTAG serial
chain. For three EZ-Boards, three JTAG cables are required. Similarly, for
four EZ-Boards, four JTAG cables are required. Note that each respective
EZ-board also requires its own power supply.
Part numbers for Samtec standard, off the shelf link port cables can be
found in “MP JTAG Out Connector (P10)” on page 2-29.

Using ADSP-21479 EZ-Board
Expansion Interface II
The expansion interface II allows an Analog Devices EZ-Extender or a
custom-design daughter board to be tested across various hardware platforms with identical expansion interfaces.
The expansion interface II implemented on the ADSP-21479 EZ-Board
consists of two connectors: a 0.1 in. shrouded header (P2) and a Samtec
QMS series header (J1). The connectors contain a majority of the
ADSP-21479 processor’s signals.
For pinout information, go to “ADSP-21479 EZ-Board Schematic” on
page B-1. The mechanical dimensions of the expansion connectors can be
obtained by contacting Technical or Customer Support.
For more information about daughter boards, visit the Analog Devices
Web site at:
http://www.analog.com/en/embedded-processing-dsp/sharc/content/sharc_development_tools/fca.html.
Limits to current and interface speed must be taken into consideration
when using the expansion interface II. Current for the expansion
interface II is sourced from the EZ-Board; therefore, the current should be
limited to 1A for 5V and 500 mA for the 3.3V planes. If more current is
required, then a separate power connector and a regulator must be
designed on a daughter card. Additional circuitry can add extra loading to
signals, decreasing their maximum effective speed.
Devices does not support and is not responsible for the
L Analog
effects of additional circuitry.
Power Measurements
Several locations are provided for measuring the current draw from various power planes. Precision 0.05 ohm shunt resistors are available on the
ADSP-21479 EZ-Board Evaluation System Manual
1-21
Power-On-Self Test
VDDRTC, VDDEXT, and VDDINT voltage domains. The associated
jumper on connectors P3, P6, or P7 must be removed to measure current
draw. Once the jumper is removed, voltage across the resistor can be measured using an oscilloscope. Once voltage is measured, current can be
calculated by dividing voltage by 0.05. For the highest accuracy, a differential probe should be used for measuring voltage across the resistor.
For more information, see “VDDRTC Power Connector (P3)” on
page 2-27, “VDDEXT Power Connector (P6)” on page 2-28, and
“VDDINT Power Connector (P7)” on page 2-28.
Power-On-Self Test
The power-on-self-test program (POST) tests all EZ-Board peripherals
and validates functionality as well as connectivity to the processor. Once
assembled, each EZ-Board is fully tested for an extended period of time
with a POST. All EZ-Boards are shipped with the POST preloaded into
one of their on-board flash memories. The POST is executed by resetting
the board and pressing the proper push button(s). The POST also can be
used for reference in custom software designs or hardware troubleshooting. Note that the source code for the POST program is included in the
VisualDSP++ installation directory along with the readme text file, which
describes how the board is configured to run a POST.

ADSP-21479 EZ-Board Evaluation System Manual
ADSP-21479 EZ-Board Hardware Reference
The input clock is 16.625 MHz. The default boot mode of the processor
is external parallel flash boot. See “Boot Mode Select Switch (SW4)” on
page 2-10 for information on how to change the default boot mode.
DAI Interface
The digital application interface (DAI) pins are connected to the signal
routing unit (SRU) of the processor. The SRU is a flexible routing system
providing a large system of signal flows within the processor. The SRU
allows you to route the DAI pins to different internal peripherals in various combinations.
The DAI connects various peripherals on the EZ-Board. Table 2-1 shows
the DAI pin names, associated peripheral and net names, switch designators through which the pins are connected to the peripherals, and default
switch settings.

responding signals. Refer to “DAI [17–20] Enable Switch (SW7)” on
page 2-11 and “External Port Enable Switch (SW13)” on page 2-12 for
more information.
Reset Push Button (SW12)
The reset push button (SW12) resets the following ICs:
• ADSP-21479 processor (U1)
• AD1939 audio codec (U19)
• Parallel flash memory (U4)
The reset also is linked to the expansion II interface; any daughter card
connected to the expansion interface that requires a reset can use SW12.
The reset push button does not reset the standalone debug agent once the
debug agent is connected to a personal computer (PC). After communication between the debug agent and PC is initialized, pushing a reset button
does not reset the USB chip on the debug agent. The only way to reset the
USB chip on the debug agent is to power down the EZ-Board.
External Port Enable Switch (SW13)
The external port enable switch (SW13) disconnects the control pins of the

Jumpers
Flash WP Jumper (JP1)
The flash WP jumper (JP1) write-protects block 0 of the parallel flash
chip. Block 0 is located at address range 0x0400 0000–0x0400 1FFF. The
POST begins at block 0 and continues on to other blocks in flash memory. When the jumper is installed on JP1, and the parallel flash driver
from Analog Devices is used, block 0 is read-only. By default, JP1 is not
installed.
S/PDIF Loopback Jumper (JP2)
The S/PDIF loop back jumper ( JP2) is used for internal testing only. The
jumper loops back any digital audio signal from the S/PDIF’s Data Out
pin to the S/PDIF’s Data In pin. By default, JP2 is not installed.
UART RTS/CTS Jumper (JP3)
The UART RTS/CTS jumper (JP3) connects the RTS and CTS pins of the
RS-232 interface. By default, JP3 is installed.
UART Loopback Jumper (JP4)
The UART loop back jumper (JP4) is used for internal testing only. The
jumper loops back UART receive data from UART transmit data. By
default, JP4 is not installed.
DSP Audio Oscillator Jumper (JP5)
The processor audio oscillator jumper (JP5) connects a 24.576 MHz
oscillator to the DAI_P17 pin of the processor. The jumper can be used to
make the processor the master and the AD1939 device—the slave. By
default, JP5 is not installed, resulting in the AD1939 being the master,
and the processor being the slave.
