Description
Power State Set (PS-Set): Writes to these bits
set the Audio Function Group to the Power State
as described below:
PSS = ’0000’b; D0 - Fully on.
PSS = ‘0001’b; D1 - Not Supported
3:0
Read/Write
0011b
PSS = ‘0010’b; D2 - Not Supported
PSS = ‘0011’b; D3 - Allows for lowest possible
power consumption under software control. See
“D3 Lower Power State Support” on page 26 for
more information.
PSS = ‘0100’b; D4 - Not Supported
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
a) the PS-Set field of the currently referenced node or b) the PS-Set field of the Audio Function Group
node under which the currently referenced node was enumerated (is controlled).
