Abstract
An IC according to the present invention contains a counter, which includes a plurality of incomplete coincidence detection circuits each associated with a different one of a corresponding number of flip-flops storing respective bit data of an aimed value, each incomplete coincidence detection circuit including a first logic element for receiving a Q or Q output of said associated flip-flop and a one-bit output from a bit location of the counter corresponding to the different flip-flop, and a second logic element for receiving an output of the first logic element and the other of the Q and Q output of the different flip-flop to provide a coincidence detection signal, the detection circuit being adapted to detect a coincidence of the aimed value with the count value when all of the incomplete coincidence detection circuits output the coincidence detection signals.
