22.2
For PIC18F1XK22/LF1XK22 devices, the WDT is
driven by the LFINTOSC source. When the WDT is
enabled, the clock source is also enabled. The nominal
WDT period is 4ms and has the same stability as the
LFINTOSC oscillator.
The 4ms period of the WDT is multiplied by a 16-bit
postscaler. Any output of the WDT postscaler is
selected by a multiplexer, controlled by bits in Configu-
ration register 2H. Available periods range from 4ms to
131.072 seconds (2.18 minutes). The WDT and post-
scaler are cleared when any of the following events
occur: a SLEEP or CLRWDT instruction is executed, the
IRCF bits of the OSCCON register are changed or a
clock failure has occurred.
