<p>PURPOSE:To reduce the number of program steps or external circuits, by providing specific counter circuit, count value transferring circuit, and D type FF to fetch data synchronously without glitch with simple circuit constitution. CONSTITUTION:A counter circuit 10 which performs counting with the first clock 1 and a count value transferring circuit including a shift register circuit 20 which converts respective bit output signals 5 of the counter circuit 10 from parallel to serial and transfers them serially with the second clock 2 having a speed higher than that of the first clock 1 are provided. Further, a D type flip-flop circuit 40 is provided with uses the second clock 2 as the clock input and receives the first clock 1 in the D input terminal to supply it as the Q output to the clock input terminal of the counter circuit 10.</p> |
