Abstract
PURPOSE:To improve reliability by preventing an erroneous read during carry operation, by stopping the counting operation of a binary counter when storing operation is performed by a read-in pulse signal, by a comparing circuit consisting of the binary counter and a latch circuit. CONSTITUTION:When the value count of a binary counter 2 is transferred to a latch circuit 3, the inputting of a clock pulse (f) to the binary counter 2 is stopped by a clock pulse control signal (e) at read-in timing, and the counting operation of the binary counter 2 is stopped, so reading operation during a transident counting period is not performed. Therefore, erroneous count contents are never read.
