9.0 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
