readback as both bits high. No other bits of the LAN91C100FD can be read or written until the EEPROM operation
completes and both bits are clear. This mechanism is also valid for reset initiated reloads.
Note: If no EEPROM is connected to the LAN91C100FD, for example for some embedded applications, the ENEEP pin
should be grounded and no accesses to the EEPROM will be attempted. Configuration, Base, and Individual Address
assume their default values upon hardware reset and the CPU is responsible for programming them for their final value.
