Windowed Watchdog Timer (WWDT) Reset

The Windowed Watchdog Timer generates a Reset if the firmware does not issue a CLRWDT instruction within the time-out period or window set. The TO and PD bits in the STATUS register and the RWDT bit are changed to indicate a WDT Reset. The WDTWV bit indicates if the WDT Reset has occurred due to a timeout or a window violation.
