Abstract
A shift register circuit generates a clock enable signal in response to a start signal and in response to a clock signal. The shift register circuit generates multiple pulses in the clock enable signal in response to a single transition in the start signal and in response to control signals having values that indicate to generate more than one pulse in the clock enable signal. A multiplexer circuit provides an output signal for testing an electronic circuit based on an input signal or based on the clock signal in response to the clock enable signal.
