An electronic device receives data from an EEPROM by sending address information to it on one set of leads and receiving data back from it through a different set of multiplexed address/data leads. The electronic device also sends and receives data to and from a data path controller by sending address information and sending or receiving data information to or from it through the set of multiplexed address/data leads. Selection of which device, the EEPROM or the data path controller, to communicate with is made by the electronic device setting appropriate values for chip select and chip enable commands. Synchronization of the sending and receiving of the address and data information is accomplished by the use of address and data strobe signals generated by the electronic device and connected, as appropriate, with the EEPROM and data path controller.
