30.5.1 WDT Time-out in Run Mode

When the WDT times out in Run mode, a device Reset/NMI is generated. Firmware can determine if the cause of the Reset was the WDT time-out in Run mode by testing the WDTO bit in RCON. WDT can be controlled to raise a device Reset or WDT generic trap on WDT time-out by modifying WDTRSTEN (FWDT[16]) bit.
