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
Timer_A3 is a 16-bit timer/counter with three capture/compare registers. Timer_A3 can support multiple
capture/compares, PWM outputs, and interval timing. Timer_A3 also has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare
registers.
