Table 348: Watchdog Timer Warning Interrupt register (WDWARNINT - 0x4000 4014) bit
The WDWINDOW register determines the highest WDTV value allowed when a watchdog
feed is performed. If a feed valid sequence completes prior to WDTV reaching the value in
WDWINDOW, a watchdog event will occur.
WDWINDOW resets to the maximum possible WDTV value, so windowing is not in effect.
