6.11.8 Watchdog Timer (WDT_A) (Link to User's Guide)

The primary function of the WDT_A 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 timer can be configured as an interval timer and can generate interrupts at selected time intervals.
