C. Design Notes
1. Power Management Interface Specification version support
Design Issue: The PCI 9030 Data Book indicates compliance with the PCI
Power Management Interface Specification revision 1.1, however the PMC
register description is compliant with revision 1.0. The PCI 9030 can support
either revision. The only differences between these revisions, with respect to
PCI 9030 support, are the Version bits [2:0] value (programmable by EEPROM),
and the descriptions for bits [8:6, 4] for which the values are read-only and return
a value of 0 regardless of revision. The Version bits value (001b or 010b), which
has no effect on PCI 9030 operation, is used by software to determine PMC
register format.
Recommendation: PMC register descriptions for revisions 1.0 and 1.1 are
listed below. If revision 1.1 rather than revision 1.0 is to be supported, program
the serial EEPROM with the Version value (010b) to overwrite the PMC register
default value, by changing the 32-bit value at EEPROM offset 18h from
48014801h to 48024801h.

Description
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 D3cold 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 D0
uninitialized state before a generic class device driver is able to
use it.
Reserved.
D1_Support. When set to 1, the PCI 9030 supports the D1
power state. Not Supported.
D2_Support. When set to 1, the PCI 9030 supports the D2
power state. Not Supported.
PME Support. Indicates power states in which the PCI 9030
may assert PME#. Values:
XXXX1 = PME# can be asserted from D0
XXXXX = The PCI 9030 does not support the D1 power state
XXXXX = The PCI 9030 does not support the D2 power state
X1XXX = PME# can be asserted from D3hot
XXXXX = PME# cannot be asserted from D3cold

Description
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 D0
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.
D1_Support. When set to 1, the PCI 9030 supports the D1
power state. Not Supported.
D2_Support. When set to 1, the PCI 9030 supports the D2
power state. Not Supported.
PME Support. Indicates power states in which the PCI 9030
may assert PME#. Values:
XXXX1 = PME# can be asserted from D0
XXXXX = The PCI 9030 does not support the D1 power state
XXXXX = The PCI 9030 does not support the D2 power state
X1XXX = PME# can be asserted from D3hot
