  • Page 27: C. Watchdog Timer Configuration 2

    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.
