watchdog timer (WDT)
The primary function of the WDT module is to perform a controlled system restart after a software problem
occurs. If the selected time interval expires, a system reset is generated. If the watchdog function is not needed
in an application, the module can be configured as an interval timer and can generate interrupts at selected time
intervals.
comparator_A
The primary function of the comparator_A module is to support precision slope analog-to-digital conversions,
battery−voltage supervision, and monitoring of external analog signals.
Timer_A3/Timer0_A3
Timer_A3/Timer0_A3 is a 16-bit timer/counter with three capture/compare registers. Timer_A3/Timer0_A3 can
support multiple capture/compares, PWM outputs, and interval timing. Timer_A3/Timer0_A3 also has extensive
interrupt capabilities. Interrupts may be generated from the counter on overflow conditions and from each of
the capture/compare registers.
