Watchdog Timer (WDT) Operation
During normal operation, a WDT time-out generates a device RESET. If the device is in SLEEP
mode, a WDT time-out causes the device to wake-up and continue with normal operation, this is
known as a WDT wake-up. The WDT can be permanently disabled by clearing the WDTE con-
figuration bit.
The postscaler assignment is fully under software control, i.e., it can be changed “on the fly” dur-
ing program execution.
In
final desired prescaler is other then 1:1. If the final prescaler value is 1:1, then a temporary pres-
cale value is set (other than 1:1), and the final prescale value is set in the last modification of the
OPTION_REG. This sequence must be followed since the value in the TMR0 prescaler is
unknown, and is being used as the WDT postscaler. If the OPTION_REG is changed without this
code sequence, the time before a WDT reset is unknown.

Note:

To avoid an unintended device RESET, the following instruction sequence (shown

WDT is disabled.
