WDCON.7, 6
—
Reserved for future use. Should not be set to 1 by user programs.
WDCON.5
WDOVF
Watchdog timer overflow flag. Set when a watchdog reset or timer overflow occurs. Cleared when
the watchdog is fed.
WDCON.4
WDRUN
Watchdog run control. The watchdog timer is started when WDRUN = 1 and stopped when
WDRUN = 0. This bit is forced to 1 (watchdog running) if the WDTE configuration bit = 1.
WDCON.3
WDCLK
Watchdog clock select. The watchdog timer is clocked by CPU clock/6 when WDCLK = 1 and by
the watchdog RC oscillator when WDCLK = 0. This bit is forced to 0 (using the watchdog RC
oscillator) if the WDTE configuration bit = 1.
WDCON.2–0 WDS2–0
Watchdog rate select.

Reset Value:
S 30h for a watchdog reset.
S 10h for other rest sources if the watchdog is enabled via the WDTE configuration bit.
S 00h for other reset sources if the watchdog is disabled via the WDTE configuration bit.
Not Bit Addressable
