ABSTRACT:
In a Plug and Play environment different kinds of EEPROMs can be used having different access protocols without having to add an additional pin to the EEPROM to indicate its type. The first type of EEPROM has a code which indicates the first type stored on a predetermined address whereas the second type of EEPROM having a different read protocol has another code which indicates the second type stored on a consecutive address. When the Plug and Play controller accesses the EEPROM for a read either the code 1 or code 2 is outputted whereby the appropriate read protocol is identified.
