Watchdog Timer (WDT+)
The primary function of the watchdog timer (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 disabled or configured as an interval timer and can
generate interrupts at selected time intervals.
Timer_A2
Timer_A2 is a 16-bit timer/counter with two capture/compare registers. Timer_A2 can support multiple
capture/compares, PWM outputs, and interval timing. Timer_A2 also has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare
registers.
