WAKE#
Open drain active low signal. This signal is
used to request that the system return from a
sleep/suspended state to service a
function-initiated wake event.
* +3.3 V aux was suspend power with power out to 3.3 V/1.1A
* +3.3 V was core power
* +1.5 V was core power with power out to 1.5 V/0.5A
