| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 31:22 | 0h | RO | Reserved Field (RESERVED0)
|
| 21 | 0h | RW | Hae Field (HAE) Hardware Autonomous Enable: If 1, then hardware may request power gating whenever it has reached an idle condition. |
| 20 | 0h | RO | Reserved Field (RESERVED1)
|
| 19 | 0h | RW | Sleep Enable Field (SLEEP_EN) SE: Sleep Enable:1 = The function may assert Sleep during power gating.0 =The function will never asset Sleep to the retention flops.Note that some platforms may default this bit to 0, others to 1. |
| 18 | 0h | RW | D3 Hen Field (D3HEN) If 1, then function will power gate when idle and the PMCSR [1:0] register in the function = b11 (D3). |
| 17 | 0h | RW | Device Idle En Field (DEVIDLEN) If 1, then the function will power gate when idle and the DevIdle register (DevIdleC [2] = 1) is set. |
| 16 | 0h | RW | Pmc Request Enable Field (PMCRE) If this bit is set to 1, the function will power gate when idle and pmc_(ip)_sw_pg_req_b =0. |
| 15:13 | 0h | RO | Reserved Field (RESERVED2)
|
| 12:10 | 2h | RW/O | Power Latency Scale Field (POW_LAT_SCALE) Power On Latency Scale |
| 9:0 | 0h | RW/O | Power Latency Value Field (POW_LAT_VALUE) Power On Latency value |
