BITS
31:0
Physical Address [31:0]
This field contains the lower 32-bits (31:0) of the Physical Address of the
Host MAC. The content of this field is undefined until loaded from the
EEPROM at power-on. The host can update the contents of this field after
the initialization process has completed.
Host MAC Address Low Register (HMAC_ADDRL)
This read/write register contains the lower 32-bits of the physical address of the Host MAC. The
contents of this register are optionally loaded from the EEPROM at power-on through the EEPROM
Loader if a programmed EEPROM is detected. The least significant byte of this register (bits [7:0]) is
loaded from address 01h of the EEPROM. The most significant byte of this register is loaded from
address 04h of the EEPROM.
