The Watchdog Timer dialog shows the current state of the on-chip Watchdog Timer. You can change watchdog settings using the controls in this dialog.

Watchdog Timer

• Timer holds the Watchdog Timer value.
• WDTS (Watchdog Timer Status Flag) is set by hardware when a Watchdog Timer reset occurs.
• WDTREL (Watchdog Timer Reload Register) holds the refresh value for the Watchdog Timer.
• WDTPSEL (Watchdog Timer Prescaler Select) is set to divide the Watchdog Timer clock by 16.
• WDT (Watchdog Timer Refresh Flag) is set to refresh the Watchdog Timer. To perform a refresh, you must set this flag immediately before setting the Watchdog Timer Start Flag (SWDT).
