10.4 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 time-out or a window violation.
