Physical Address [47:32]. This field contains the upper 16-bits (47:32) of the Physical Address of
the LAN9217 device. 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.
ADDRH—MAC Address High Register
The MAC Address High register contains the upper 16-bits of the physical address of the MAC. The
contents of this register are optionally loaded from the EEPROM at power-on through the EEPROM
Controller if a programmed EEPROM is detected. The least significant byte of this register (bits [7:0])
is loaded from address 0x05 of the EEPROM. The second byte (bits [15:8]) is loaded from address
0x06 of the EEPROM. Please refer to
details the byte ordering of the ADDRL and ADDRH registers with respect to the reception of the
Ethernet physical address.
