Aux Current
These three bits report the maximum 3.3 Vaux current requirements for
AN985B/BX. If bit 31 of PMR0 is ‘1’, the default value is 0101B, means
AN985B/BX need 100 mA to support remote wake-up in D3cold power
state.

Device Specific Initialization
The Device Specific Initialization bit indicates whether special
initialization of this function is required before the generic class device
driver is able to use it.
0B
, indicates that the function does not require a device specific
initialization sequence following transition to the D0 un-initialized
state

PME Clock
When “1” indicates that the AN985B/BX relies on the presence of the
CARDBUS clock for PME#/CSTSCHG operation. While “0” indicates the
no CARDBUS clock is required for the AN985B/BX to generate
PME#/CSTSCHG.
