each EEPROM operation.
MAC Address Reload
The MAC address can be reloaded from the EEPROM via a host command to the E2P_CMD register.
If a value of 0xA5h is not found in the first address of the EEPROM, the EEPROM is assumed to be
un-programmed and MAC Address Reload operation will fail. The “MAC Address Loaded” bit indicates
a successful load of the MAC address. The EPC_LOAD bit is set after a successful reload of the MAC
address.
