IMPORTANT!!!
Beware of static electricity, don't touch the components directly.
Never disconnect a target board from the USB programmer if still
plugged into the computer or from the battery unit with jumper on.
Otherwise you destroy the board!

Peripherals
A computer peripheral is a auxiliary device that
connects to and works with a computer.
A peripheral expands the computer's capabilities but
does not form part of the core computer architecture.
Peripheral
Timer_A/B
Timer_A/B are 16-bit
timer/counters with three
capture/compare registers
• Capture external signals
• Compare PWM mode
• SCCI latch for
asynchronous
communication

Peripheral
Watchdog Timer
WDT module performs a
controlled system restart
after a software problem
occurs
• Can serve as an interval timer
(generates interrupts)
• WDT Control register is
password protected
• Note: Powers-up active
