ABSTRACT:
An apparatus comprising a plurality of flip-flops and a compare circuit. The flip-flops may each be configured to (i) receive a clock signal and an input signal and (ii) generate an output signal. The flip-flops may be configured in series such that the output signal of a first of the flip-flops is presented as the input signal to a second of the flip-flops. The compare circuit may be configured to generate a reset signal in response to each of the output signals. The reset signal is generated until each of the output signals matches a set of predetermined values stored in the compare circuit.
