26.4.7.1 Operation Overview

If an expected event fails to arrive before the WDT time-out period expires, the PTG module:

Aborts the (failing) command underway.
Halts the sequencer (PTGSTRT = 0).
Sets PTGWDTO = 1.
Issues a Watchdog Timer error interrupt to the processor.

The user can either use the Watchdog Timer error interrupt or periodically poll the PTGWDTO bit (PTGCON[6]) to determine that a WDT event has occurred.
