PS-Set is a PowerState field which defines the current power setting of the referenced node. Since this
node is of type other than an Audio Function Group node, the actual power state is a function of both this
setting and the PowerState setting of the Audio Function Group node under which this node was enumer-
ated (is controlled).
PS-Act is a PowerState field which indicates the actual power state of this node. Within the Audio Func-
tion Group node, this field will always be equal to the PS-Set field (modulo the time required to execute a
power state transition). Within this type of node, this field will be the lower power consuming state of either

Power State Settings Reset (PS-SettingsRe-
set): This bit is set to ‘1’b when, during any type
of reset or low power state transition, the settings
within this widget that were changed from the
defaults, either by software or hardware, have
been reset back to their default state. When
these settings have not been reset, this is
reported as ‘0’b. This bit is always a ‘1’b follow-
ing a POR condition.

Power State Clock Stop OK(PS-ClkStopOK):
This bit is not supported and will always return
‘0’b when read.
Power State Error (PS-Error): This bit is not
supported and will always return ‘0’b when read.
Power State Actual (PS-Act): This field indi-
cates the actual power state of the referenced
node. The default state is D3.
Power State Set (PS-Set): Writes to these bits

PSS = ’0000’b; D0 - Fully on.
PSS = ‘0001’b; D1 - Not Supported
PSS = ‘0010’b; D2 - Not Supported
PSS = ‘0011’b; D3 - Allows for lowest possible
power consumption under software control. See
