The subject invention is an interface circuit between a requesting device and a responding device. The circuit comprises a flip-flop responsive to a request signal received from the requesting device and a handshake signal received from the responding device to generate a control signal. The circuit also comprises a gate for receiving the control and handshake signals and generating an acknowledge signal. The removal of the request signal sets the control signal to a first value which disables the gate and removal of the handshake signal resets the control signal to a second value which enables the gate.
