S3 Power Gating Policies (S3_PWRGATE_POL) – Offset 1828
This register contains policy bits to configure various power gating options while the system is in S3. Note that setting any of these policies to [quote]enabled[quote] may not directly result in power gating - in some cases other HW qualifications may be dynamically applied.
This register is in the RTC power well and is reset by rtc_pwrgood_rst_b.
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 31:2 | 0h | RO | Reserved |
| 1 | 0h | RW | S3 Power Gate Enable in DC Mode: SUS Well (S3DC_GATE_SUS) A '1' in this bit enables power gating of the SUS well in S3 while operating on DC power (based on the AC_PRESENT pin value). |
| 0 | 0h | RW | S3 Power Gate Enable in AC Mode: SUS Well (S3AC_GATE_SUS) A '1' in this bit enables power gating of the SUS well in S3 while operating on AC power (based on the AC_PRESENT pin value). |
