決めることのできるアツプダウンカウンタ。[Claim for Utility Model Registration] External pulses are input from the CNTR terminal and the number of pulses is counted. Depending on the port input when counting, it is possible to select from the outside whether the counter is an up counter or a down counter, and the register An up-down counter that allows you to determine the maximum value of the counter by setting a value.
