C. Watchdog Timer Configuration
The WDT is used to generate a variety of output signals after a user
programmable count. The WDT is suitable for use in the prevention of system
lock-up, such as when software becomes trapped in a deadlock. Under these
sorts of circumstances, the timer will count to zero and the selected outputs
will be driven. Under normal circumstance, the user will restart the WDT at
regular intervals before the timer counts to zero.
