PME Support — RO. This field indicates PME# can be generated from all D states.
Reserved.
Auxiliary Current — RO. This field reports 375 mA maximum Suspend well current
required when in the D3
Device Specific Initialization (DSI) — RO. This bit indicates that no device-specific
initialization is required.
Reserved — RO.
PME Clock (PMEC) — RO. This bit indicates that PCI clock is not required to generate
PME#.
Version (VS) — RO. This field indicates support for Revision 1.1 of the PCI Power
Management Specification.
PME Status (PMES) — R/WC.
0 = Software clears this bit by writing a 1 to it.
1 = This bit is set when the AC ’97 controller would normally assert the PME# signal
Reserved — RO.
PME Enable (PMEE) — R/W.
0 = Disable.
1 = Enable. When set, and if corresponding PMES is also set, the AC '97 controller sets
Reserved — RO.
Power State (PS) — R/W. This field is used both to determine the current power state
of the AC ’97 controller and to set a new power state. The values are:
00 = D0 state
01 = not supported
10 = not supported
11 = D3
When in the D3
the I/O and memory spaces are not. Additionally, interrupts are blocked.
If software attempts to write a value of 10b or 01b in to this field, the write operation
must complete normally; however, the data is discarded and no state change occurs.
