ABSTRACT:
A universal bus interface circuit can be used in conjunction with either synchronous or asynchronous bus systems. An input terminal is monitored to determine if the bus is synchronous or asynchronous. If the bus is asynchronous, a synchronization circuit generates a synchronous control signal for internal use from an asynchronous select signal. The synchronization circuit also generates an asynchronous hand-shake or acknowledge signal which is applied to the input terminal to indicate completion of the operation. The input terminal is monitored by a host processor.
