ABSTRACT:
A host control interface for use in interfacing an external host processor with internal control/status registers of an integrated circuit is provided. In accordance with the teachings of the present invention, the control interface selectively couples the integrated circuit with an interchangeable one of a variety of host processor types. In one embodiment, the control interface supports processors having a multiplexed address/data port as well as processors having separate address and data ports. Similarly, in one embodiment, the control interface supports processors utilizing a transfer start indication signal in cooperation with a read/write signal, as well as processors utilizing separate read/write strobes.
