Power-Management Control and Status Register (CPMC Offset 54H)
The CMPC register is a power-management control and status register. This register can control and sate power
management events. The following table shows the CMPC register bit fields.

PME_Status
This bit indicates that the KSZ8841-PMQL has detected a power-
management event. If bit PME_Enable is set, the KSZ8841-PMQL also
asserts the PME_N pin. This bit is cleared on power-up reset or by write
1. It is not modified by either hardware or software reset. When this bit is
cleared, the KSZ8841-PMQL deserts the PME_N pin.

PME_Enable
If this bit is set, the KSZ8841-PMQL can assert the PME_N pin.
Otherwise, assertion of the PME_N pin is disabled. This bit is cleared on
power-up reset only and is not modified by either hardware or software
reset.

No Soft Reset
If this bit is set (“1”), the KSZ8841-PMQL does not perform an internal
reset when transitioning from D3_hot to D0 because of PowerState
commands. Configuration context is preserved. Upon transition from
D3_hot to the D0 Initialized state, no additional operating system
intervention is required to preserve configuration context beyond writing
the PowerState bits.
If this bit is cleared (“0”), the KSZ8841-PMQL does perform an internal
reset when transitioning from D3_hot to D0 via software control of the
PowerState bits. Configuration context is lost when performing the soft
reset. Upon transition from D3_hot to the D0 state, full reinitialization
sequence is needed to return the device to D0 Initialized.
Regardless of this bit, devices that transition from D3_hot to D0 by a
system or bus segment reset will return to the device state D0
Uninitialized with only PME context preserved if PME is supported and
enabled.

Power State
This field is used to set the current power state of the KSZ8841-PMQL
and to determine its power state. The definitions of the field values are:
0: D0
1: D1
2: D2
3: D3(hot)
This field gets a value of 0 after power up.
