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 instruction.
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 (Watchdog
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
WDT time-out period values may be found in the
Electrical Specifications section under TWDT (parameter
#31). Values for the WDT prescaler (actually a
postscaler, but shared with the Timer0 prescaler) may be
assigned using the OPTION register.
.
FIGURE 9-14:
WATCHDOG TIMER BLOCK DIAGRAM
TABLE 9-7:
SUMMARY OF REGISTERS ASSOCIATED WITH WATCHDOG TIMER
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.
