Abstract
Interface circuitry for an integrated circuit is provided, which can operate in accordance with any one of several different protocols. Protocol identifying circuitry within the interface monitors signals passed from a master/host device to the integrated circuit. Based upon the characteristics of the signals, the protocol being used by the master/host device can be determined, and the interface circuitry on the integrated circuit may be configured accordingly. The protocol identifying circuitry 'remembers' which protocol is in use, so that the interface circuit remains configured for the correct protocol regardless of subsequent changes in the signals from the master/host device.
