Descriptions
PME_Support.
The AN983B will assert PME# signal while in the D0, D1, D2,
D3 power state. The AN983B supports Wake-up from the
above states.
D2_Support. The AN983B supports D2 Power Management
State.
D1_Support. The AN983B supports D1 Power Management
State.
Aux Current. These three bits report the maximum 3.3 Vaux
current requirements for AN983B. If bit 31 of PMR0 is ‘1’, the
default value is 0101b, means AN983B need 100 mA to
support remote wake-up in D3cold power state.
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.
0: indicates that the function does not require a device
specific initialization sequence following transition to the D0
un-initialized state.
Reserved.
PME Clock. When “1” indicates that the AN983B relies on the
presence of the PCI clock for PME# operation. While “0”
indicates the no PCI clock is required for the AN983B to
generate PME#.
Version. The value of 010b indicates that the AN983B
complies with Revision 1.1 of the PCI Power Management
Interface Specification.
Next Item Pointer. This value is always 0h, indicates that
there is no additional items in the Capabilities List.
Capability Identifier. This value is always 01h, indicates the
link list item as being PCI Power Management Registers.

PME_Status, This bit is set when the AN983B would normally
assert the PME# signal for wake-up event, this bit is
independent of the state of the PME-En bit.
Writing a “1” to this bit will clear it and cause the AN983B to
stop asserting a PME# (if enabled). Writing a “0” has no
effect.
Data_Scale, indicates the scaling factor to be used when
