Power Management Configuration Reg 2 (PM_CFG2) – Offset 183c
This register contains misc. fields used to configure the processor power management behavior.
This register is in multiple power wells and reset domains (see below).
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 31:29 | 0h | RW | Power Button Override Period (PBOP) This field determines, while the power button remains asserted, how long the PMC |
| 28 | 0h | RW/L | Power Button Native Mode Disable (PB_DIS) When this bit is '0' (default), the PMC's power button logic will act upon the input value |
| 27 | 0h | RO | Reserved |
| 26 | 0h | RW/V | DRAM_RESET# Control (DRAM_RESET_CTL) BIOS uses this bit to control the DRAM_RESET# pin, which is routed to the reset pin on the DRAM. |
| 25:21 | 0h | RO | Reserved |
| 20:8 | 0h | RO | Reserved (RSVD) Reserved |
| 7:0 | c7h | RW/L | Reset Power Cycle Duration (PWR_CYC_DUR) The value in this register determines the minimum time a platform will stay in reset (SLP_S3#, SLP_S4#, SLP_S5# asserted and also SLP_A# and SLP_LAN# asserted if applicable) during a host partition reset with power cycle, Sx, G3 exit or a global reset. |
