A flip-flop circuit includes a flip-flop, a first pass gate, a second pass gate, and a third pass gate. The first pass gate has an input to receive an input signal, an output coupled to the flip-flop's data input, and a control terminal to receive a first control signal. The second pass gate has an input coupled to the flip-flop's data input, an output coupled to the circuit's output, and a control terminal to receive a second control signal. The third pass gate has an input coupled to the flip-flop's data output, an output coupled to the circuit's output, and a control terminal to receive a third control signal. The first, second, and third control signals may be generated in response to various logical combinations of a bypass signal and a clock enable signal.
