S5 Power Gating Policies (S5_PWRGATE_POL) – Offset 1830
This register contains policy bits to configure various power gating options while the system is in S5. 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.
