MAC/PHY and Control Registers
MAC Address Register Low (0x0200): MARL
This register along with the other two MAC address registers are loaded starting at word location 0x10 of the EEPROM
upon hardware reset. The register can be modified by the software driver, but will not modify the original MAC address
value in the EEPROM. The MAC address is used to define the individual destination address that the KSZ8842-
PMQL/PMBL host port will respond to when receiving unicast frames. This MAC address will become the source
address when sending unicast frames from the host port to port-1 or port-2. 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 right to left (LSB to MSB). The actual transmitted and received bits are in the order of 10000000
11000100 10100010 11100110 10010001 11010101.
The following table shows the register bit fields for low word of MAC address.

MAC Address Register Middle (0x0202): MARM
This register along with the other two MAC address registers are loaded starting at word location 0x10 of the EEPROM
