R/W
W
Disables the internal voltage reference.
Arm the autowake timer. Writing a 1 to this bit arms the autowake
timer and presets it with the values presently in WAKE_PRD and
WAKE_RES . The autowake timer is reset and disarmed whenever
the processor is in MISSION mode or BROWNOUT mode. The
timer must be armed at least three crystal clock cycles before the
SLEEP or LCD-ONLY mode is commanded.

R/W
The WD overflow status bit. This bit is set when the WD timer
overflows. It is powered by the nonvolatile supply and at bootup will
indicate if the part is recovering from a WD overflow or a power fault.
This bit should be cleared by the MPU on bootup. It is also
automatically cleared when RESET is high.
