Bit
Description
15-11(r)
PME support
This 5-bit field indicates the power states in which the function may assert PME.
Value is set to 11001 b if V
AUX_AV
= 1 to indicate PME can be asserted from
D3cold and D0. If V
AUX_AV
= 0, this field is set to 01001b to indicate PME can be
asserted from D3hot and D0.
The entire setting can be overwritten by BIOS via writing to 6Ah, or an external
EEPROM. If V
AUX_AV
= 0, bit 15 shall always be zero. If V
AUX
= 1, bit 15 shall
reflect the setting of 6Ah, or that loaded from EEPROM.
10(r)
D2 support
This bit is set to ‘0’ to indicate that function does not support the D2 power
management state. This setting can be overwritten by BIOS via 6Ah, or with the
external EEPROM.
9(r)
D1 support
This bit is set to ‘0’ to indicate that function does not support the D1 power
management state. This setting can be overwritten by BIOS via 6Ah, or with the
external EEPROM.
8-6(r)
Aux_Current
These bits are set to ‘0’ for PCI-PM 1.0 compliance. For PCI-PM 1.1 compliance,
these bits are overwritten by BIOS via 6Ah, or loaded from an external EEPROM
to reflect the 3.3V
AUX
current requirement.
5(r)
DSI
The Device Specific Initialization bit indicates whether special initialization of this
function is required (beyond the standard PCI configuration header) before the
generic class device driver is able to use it. This register is set to ‘0’ to indicate
that it does not require special initialization.
4(r)
Reserved.
3(r)
PME Clock
This bit is a ‘0’, indicating that the function does not rely on the presence of the
PCI clock for PME operation.
2:0(r)
Version
This register is set to 001b, indicating that this function complies with Rev 1.0 of
the PCI Power Management Interface Specification These bits can also be
overwritten by BIOS via 6Ah, or loaded from an external EEPROM to 010b for
compliance with PCI-PM 1.1.
