10.5 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. When a WDT Time-out Reset occurs, the TO bit of the STATUS register and the RWDT bit are cleared. If the CLRWDT instruction was issued while the WDT Reset window was closed, the WDTWV bit is cleared, indicating a WDT Window violation occurred.
