Address Offset: 70h–73h Attribute: R/W
Default Value: 00000000h Size: 32 bits
3 No_Soft_Reset (NSR) — RO. This bit indicates that when the Intel MEI host controller is
transitioning from D3
hot
to D0 due to a power state command, it does not perform an internal reset.
Configuration context is preserved.
2 Reserved
1:0 Power State (PS) — R/W. This field is used both to determine the current power state of the Intel
MEI host controller and to set a new power state. The values are:
00 = D0 state (default)
11 = D3
hot
state
The D1 and D2 states are not supported for the Intel MEI host controller. When in the D3
hot
state,
the Intel ME’s configuration space is available, but the register memory spaces are not. Additionally,
interrupts are blocked.
