WATCHDOG TIMER (WDT)

The Watchdog Timer is a system timer that generates
a Reset if the firmware does not issue a 

CLRWDT

instruction within the time-out period. The Watchdog
Timer is typically used to recover the system from
unexpected events.
The WDT has the following features:
• Independent clock source
• Multiple operating modes

- WDT is always on
- WDT is off when in Sleep
- WDT is controlled by software
- WDT is always off

• Configurable time-out period is from 1 ms to 256 

seconds (nominal)

• Multiple Reset conditions
• Operation during Sleep
