264 / 304 page  264 Am79C973/Am79C975 P R E L I M INARY Register Summary Note: RO = Ready Only, RC = Read/Auto-Clear, RW = Read/Write, W = Write, WO = Write Only Am79C975 EEPROM Map The Am79C975 PCnet-FAST III controller uses an ex- tended EEPROM map compared to the Am79C973 de- vice (locations reserved in Am79C973 EEPROM map), since there are some new registers in the SMIU that are loaded from the EEPROM.
