24.2
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/CLKI pin. That means that
the WDT will run even if the clock on the OSC1/CLKI
and OSC2/CLKO/RA6 pins of the device has 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 (Watch-
dog Timer wake-up). The TO bit in the RCON register
will be cleared upon a WDT time-out.
The Watchdog Timer is enabled or disabled by a device
configuration bit, WDTEN (CONFIG2H<0>). If WDTEN
is set, software execution may not disable this function.
When WDTEN is cleared, the SWDTEN bit enables or
disables the operation of the WDT.

The WDT time-out period values may be found in the
Electrical Specifications section under parameter 31.
Values for the WDT postscaler may be assigned using
the configuration bits.
24.2.1
Register 24-15 shows the WDTCON register. This is a
readable and writable register which contains a control
bit that allows software to override the WDT enable
configuration bit only when the configuration bit has
disabled the WDT.
