| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 15:11 | 18h | RO/V | PME Support (PMES) Indicates PME# can be generated from D3 states. |
| 10 | 0h | RO | D2 Support (D2S) The D2 state is not supported. |
| 9 | 0h | RO | D1 Support (D1S) The D1 state is not supported. |
| 8:6 | 1h | RO/V | Aux Current (AC) Reports 55 mA maximum Primary well current required when in the D3cold state. |
| 5 | 0h | RO | Device Specific Initialization (DSI) Indicates that no device-specific initialization is required. |
| 4 | 0h | RO | Immediate Readiness on Return to D0 (IRR2D0) If this bit is a '1', this Function is guaranteed to be ready to successfully complete valid accesses immediately after being set to D0. These accesses include Configuration cycles, and if the Function returns to D0active, they also include Memory and I/O Cycles. |
| 3 | 0h | RO | PME Clock (PMEC) Does not apply. Hardwired to 0. |
| 2:0 | 3h | RO | Spec Version (VS) Indicates support for Revision 1.2 of the PCI Power Management Specification. |
