PIC18F2XK20/4XK20
23.2
For PIC18F2XK20/4XK20 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 4 ms and has the same stability as the LFIN-
TOSC oscillator.
The 4 ms 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 4 ms
to 131.072 seconds (2.18 minutes). The WDT and
postscaler 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.
