Bank 2 Host MAC Address Register Low (0x00): MARL
This register along with the other two Host MAC address registers are loaded starting at word location 0x1 of the
EEPROM upon hardware reset. The software driver can modify the register, but it will not modify the original Host MAC
address value in the EEPROM. These six bytes of Host MAC address in external EEPROM are loaded to these three
registers as mapping below:
MARL[15:0] = EEPROM 0x1(MAC Byte 2 and 1)
MARM[15:0] = EEPROM 0x2(MAC Byte 4 and 3)
MARH[15:0] = EEPROM 0x3(MAC Byte 6 and 5)
The Host MAC address is used to define the individual destination address that the KSZ8841M responds to when
receiving frames. Network addresses are generally expressed in the form of 01:23:45:67:89:AB, where the bytes are
received from left to right, and the bits within each byte are received from right to left (LSB to MSB). For example, the
actual transmitted and received bits are on the order of 10000000 11000100 10100010 11100110 10010001 11010101.
These three registers value for Host 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
