Abstract
Communication systems, circuits, circuit systems and methods of operating a circuit are provided. According to one aspect of the invention, a circuit configured to operate in a functional mode and a test mode includes a flip-flop including a control input; logic circuitry configured to generate a control signal to control an operation of the flip-flop; and control circuitry configured to selectively provide the control signal to the control input of the flip-flop during testing of the circuit in the test mode. A method of operating a circuit according to another aspect of the invention includes providing a circuit having a flip-flop; operating the circuit in a functional mode; testing the circuit; generating a control signal to control an operation of the flip-flop; and selectively providing the control signal to a control input of the flip-flop during the testing of the circuit.
