Register 10-27. (PMC; PCI:42h) Power Management Capabilities
(PCI Power Mgmt. r1.0)
Bit
Description
Read
Write
Value after
Reset
2:0
Version.
The value 001 indicates compliance with
PCI Power
Mgmt. r1.0.
PCI Clock Required for PME# Signal.
When set to 1,
indicates a function relies on PCI clock presence for PME#
operation. The PCI 9030 does not require the PCI clock for
PME#, so this bit should set to 0.
Auxiliary Power Source.
Because the PCI 9030 does not
support PME# while in a D
3
cold state, this bit is always set to 0.
Not Supported.
Device-Specific Initialization (DSI).
When set to 1, the PCI
9030 requires special initialization following a transition to a D
0
uninitialized state before a generic class device driver is able to
use it.
Reserved.
D
1
_Support.
When set to 1, the PCI 9030 supports the D
1
power state.
Not Supported.
D
2
_Support.
When set to 1, the PCI 9030 supports the D
2
power state.
Not Supported.
PME Support.
Indicates power states in which the PCI 9030
may assert PME#. Values:
XXXX1 = PME# can be asserted from D
0
XXXXX = The PCI 9030 does not support the D
1

XXXXX = The PCI 9030 does not support the D

2:0
Version.
The default value 001 indicates compliance with
PCI
Power Mgmt. r1.0
. To instead indicate PMC register format
compliance with Revision 1.1, this value should be set to 010.
PCI Clock Required for PME# Signal.
When set to 1,
indicates a function relies on PCI clock presence for PME#
operation. The PCI 9030 does not require the PCI clock for
PME#, so this bit should set to 0.
Reserved.
Device-Specific Initialization (DSI).
When set to 1, the PCI
9030 requires special initialization following a transition to a D
0
uninitialized state before a generic class device driver is able to
use it.
Aux_Current.
Supported by way of the PMDATA register per
PCI Power Mgmt. r1.1.
