Watchdog Timer (WDT)

The Watchdog Timer is a free running, on-chip, RC
oscillator which does not require any external
components. This RC oscillator is separate from the
RC oscillator of the OSC1/CLKIN pin. That means that
the WDT will run, even if the clock on the OSC1/CLKIN
and OSC2/CLKOUT pins of the device have been
stopped, for example, by execution of a 

SLEEP

 instruc-

tion.

During normal operation, a WDT time-out generates a
device Reset (Watchdog Timer Reset). If the device is
in Sleep mode, a WDT time-out causes the device to
wake-up and continue with normal operation (Watch-
dog Timer Wake-up). The TO bit in the Status register
will be cleared upon a Watchdog Timer time-out.

The WDT can be permanently disabled by clearing
configuration bit WDTE (Section 9.1 “Configuration
Bits”).

WDT time-out period values may be found in the
Electrical Specifications section under T

WDT

 (parame-

ter #31). Values for the WDT prescaler (actually a
postscaler, but shared with the Timer0 prescaler) may
be assigned using the OPTION_REG register. 

.

FIGURE 9-15:

SUMMARY OF WATCHDOG TIMER REGISTERS

Note:

The 

CLRWDT

 and 

SLEEP

 instructions clear

the WDT and the postscaler, if assigned to
the WDT, and prevent it from timing out
and generating a device Reset condition.

Note:

When a 

CLRWDT

 instruction is executed

and the prescaler is assigned to the WDT,
the prescaler count will be cleared, but the
prescaler assignment is not changed.
