Wake Alarm Device Timer: AC (WADT_AC) – Offset 1800
Bits in this register only need to be valid for reading when the Main power well is up. However, since some of the events may initially be detected while the Main power well and SUS well are down, they are marked as DSW bits.

31:0 | ffffffffh | RW/V | Wake Alarm Device Timer Value for AC Mode (WADT_AC_VAL) This field contains the 32-bit wake alarm device timer value (granularity 1s) for AC power. The timer begins decrementing when written to a value other than FFFFFFFFh (regardless of the power source when the write occurs). Upon counting down to 0: |
