Description
PS-Act. Actual Power State [1:0].
00: Power state is D0
01: Power state is D1
10: Power state is D2
11: Power state is D3
PS-Act indicates the actual power state of the referenced node. For Audio Function Group nodes
(NID=01h), PS-Act is always equal to PS-Set.
00: Power state is D0
01: Power state is D1
10: Power state is D2
11: Power state is D3
PS-Set controls the current power setting of the referenced node.
Description
PS-Act. Actual Power State [1:0]
00: Power state is D0
01: Power state is D1
10: Power state is D2
11: Power state is D3
PS-Act indicates the actual power state of the referenced node. The actual power state of the referenced
node is also controlled by Audio Function (NID=01h), the PS-Set setting of the referenced node is used
to provide fine-grained power control
00: Power state is D0
01: Power state is D1
10: Power state is D2
11: Power state is D3
PS-Set controls current power setting of referenced node
