10.0
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
• Configurable time-out period is from 1 ms to 256
• Multiple Reset conditions
• Operation during Sleep
