These three registers value for MAC address 01:23:45:67:89:AB will be held as below:
MARL[15:0] = 0x89AB
MARM[15:0] = 0x4567
MARH[15:0] = 0x0123
The following table shows the register bit fields for low word of MAC address.

RW
MARL MAC Address Low
The least significant word of the MAC address
MAC Address Register Middle (0x0202): MARM
The following table shows the register bit fields for middle word of MAC address.

MAC Address Register High (0x0204): MARH
The following table shows the register bit fields for high word of MAC address.
Bit
Default
R/W
Description
15-0

RW
MARH MAC Address High
The Most significant word of the MAC address
On-Chip Bus Control Register (Offset 0x0210): OBCR
This register controls the on-chip bus speed for the KSZ8841-PMQL operations. It’s used for power management when
the external host CPU is running a slow frequency. The default of the on-chip bus speed is 25MHz. When the external
host CPU is running at a higher clock rate, it’s recommended the on-chip bus is adjusted accordingly for the best
performance.

EEPROM Control Register (Offset 0x0212): EEPCR
KSZ8841-PMQL supports both with and without EEPROM system design. To support external EEPROM, tie the
EEPROM Enable (EEEN) pin to high; otherwise, tie it to Low (or no connect). Also, KSZ8841-PMQL allows software to
access (read and write) EEPROM directly. That is, the EEPROM access timing can be fully controlled by software if
EEPROM Software Access bit is set.
