摘要：
A frequency divider circuit having N flip-flops connected in series, includes a logic circuit for monitoring at least one of the outputs of the N flip-flops and halting the frequency division operation of a prior stage flip-flop when the value of the output which is monitored is equal to a predetermined value when a reset signal is input, and restarting frequency division operation when the reset signal is cancelled.
