Description
PME_ Support (Fixed Value: 0x09)
Indicates that the PME* signal can be output from the state where the bit is
set to “1”.
Bit 15: Can output the PME* signal from the D3cold state.
Bit 14: Can output the PME* signal from the D3hot state.
Bit 13: Can output the PME* signal from the D2 state.
Bit 12: Can output the PME* signal from the D1 state.
Bit 11: Can output the PME* signal from the D0 state.
Note:
signal from the D0 and the D3hot states.
D2_Support (Fixed Value: 0)
0: Indicates that the D2 state is not supported.
D1_Support (Fixed Value: 0)
0: Indicates that the D1 state is not supported.
DSI (Fixed Value: 0)
0: Indicates that Device Specific Initialization is not required.
PME Clock (Fixed Value: 0)
0: Indicates that the PCI Clock is not required to assert the PME* signal.
Version (Fixed Value: 0x2)
2: Indicates compliance with "PCI Power Management Interface
Specification" Version 1.1.
