effect.
Since the AN983B doesn’t supports PME# from D3cold, this
bit is defaulted to “0”.
Data_Scale, indicates the scaling factor to be used when
interpreting the value of the Data register. This field is
required for any function that implements the Data register.
Otherwise, it’s optional.
The AN983B doesn’t support Data register and Data_Scale.
Data_Select, This four bit field is used to select which data is
to be reported through the Data register and Data_Scale
field. This field is required for any function that implements
the Data register.
The AN983B doesn’t support Data_select.
PME_En, “1” enables the AN983B to assert PME#. When “0”
disables the PME# assertion.
This bit defaults to “0” if the function does not support PME#
generation from D3cold.
Reserved.
PowerState, This two bit field is used both to determine the
current power state of the AN983B and to set the AN983B
into a new power state. The definition of this field is given
below.
00b - D0
01b - D1
10b - D2
11b - D3hot
If software attempts to write an unsupported, optional state
to this field, the write operation must complete normally on
the bus, however the data is discarded a no state change
occurs.
