15
Reserved

NO_SRST
No Soft Reset
When this bit is set, indicates that KSZ8841M transitioning from D3_hot to D0 because
of PowerState commands do not perform an internal reset. Configuration Context is
preserved. Upon transition from the D3_hot to the D0 Initialized state, no additional
operating system intervention is required to preserve Configuration Context beyond
writing the PowerState bits.
When this bit is clear, KSZ8841M performs an internal reset upon transitioning from
D3_hot to D0 via software control of the PowerState bits. Configuration Context is lost
when performing the soft reset. Upon trasition from the 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.
This bit is loaded to bit 3 of PMCS register
13
Reserved
Reserved.
12
PME_D2
PME Support D2
When this bit is set, the KSZ8841M asserts PME event (pin 14) when the KSZ8841M is
in D2 state and PME_EN is set. Otherwise, the KSZ8841M does not assert PME event
when the KSZ8841M is in D2 state.
This bit is loaded to bit 13 of PMCR register
11
PME_D1
PME Support D1
When this bit is set, the KSZ8841M asserts PME event (pin 14) when the KSZ8841M is
in D1 state and PME_EN is set. Otherwise, the KSZ8841M does not assert PME event
when the KSZ8841M is in D1 state.
This bit is loaded to bit 12 of PMCR register.
10
D2_SUP
D2 Support
When this bit is set, the KSZ8841M supports D2 power state. This bit is loaded to bit 10
of PMCR register.
9
D1_SUP
D1 Support
When this bit is set, the KSZ8841M supports D1 power state. This bit is loaded to bit 9
of PMCR register.

Clock_Rate
Internal clock rate selection
0: 125 MHz
1: 25 MHz
Note: At power up, this chip operates on 125 MHz clock. The internal frequency can be
dropped to 25 MHz via the external EEPROM.
0
ASYN_8bit
Async 8-bit bus select
1= bus is configured for 16-bit width
0= bus is configured for 8-bit width
This bit is loaded to bit 0 of PMCR register
(32-bit width, KSZ8841-32MQL, don’t care this bit setting)
