Global Soft Reset
= 1 software reset is active.
= 0 software reset is inactive.
Software reset will affect PHY, MAC, QMU, DMA, and the switch core, only the BIU
(base address registers) remains unaffected by a software reset.
Bank 3 Power Management Capabilities Register (0x08): PMCR
This register is a read-only register that provides information on the K8841M power management capabilities. These
bits are automatically downloaded from Configparam word of EEPROM , if pin EEEN is high (enabled EEPROM)
Bit
Default Value

Description
15
0
RO
PME Support D3 (cold)
This bit defaults to 0, so the KSZ8841M does not support D3(cold)
14
1
RO
PME Support D3 (hot)
This bit is 1 only,it is indicating that the KSZ8841M can assert PME event (PMEN pin
14) in D3(hot) power state.(see bit1:0 in PMCS register)
13
0
RO
PME Support D2
If this bit is set, the wake-up signals will assert PME event (PMEN pin 14) when the
KSZ8841M is in D2 power state and PME_EN (see bit8 in PMCS register) is set.
Otherwise, the KSZ8841M does not assert PME event (PMEN pin 14) when the
KSZ8841M is in D2 power state.
The value of this bit is loaded from the PME_D2 bit of 0x6 in the serial EEPROM
(without an EEPROM, this bit defaults to 0).
12
0
RO
PME Support D1
If this bit is set, the wake-up signals will assert PME event (PMEN pin 14) when the
KSZ8841M is in D1 power state and PME_EN (see bit8 in PMCS register) is set.
Otherwise, the KSZ8841M does not assert PME event (PMEN pin 14) when the
KSZ8841M is in D1 power state.
The value of this bit loaded from the PME_D1 bit of 0x6 in the serial EEPROM (without
an EEPROM, this bit defaults to 0).
11
0
RO
PME Support D0
This bit defaults to 0, it is indicating that the KSZ8841M does not assert PME event
