Physical Address [47:32]
This field contains the upper 16-bits (47:32) 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 High Register (HMAC_ADDRH)
This read/write register contains the upper 16-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 05h of the EEPROM. The second byte (bits [15:8]) is loaded from address 06h
of the EEPROM.
HMAC_ADDRL and HMAC_ADDRH registers with respect to the reception of the Ethernet physical
address. Please refer to
more information on the EEPROM Loader.
