Abstract

PURPOSE:To simplify the control system of a counting circuit, by providing a selector, a decoder and a timing signal forming circuit, and using the output of a plurality of counting circuits as a control circuit to a storage circuit in common in time division. CONSTITUTION:Storage areas are assigned to an ROM210 corresponding to counters 200-20n. A timing forming circuit 230 transmits a timing pulse 280 which can select once for output pulses 250-25n of the counters 200-20n being the input of a selector 250 during one period of the input pulse on an input pulse signal line 240, counter clear pulses 290-29n of a decoder. A selector 205 takes inputs the counter output pulses 250-25n and selects one of the counter output pulses with the timing pulse 280 and transmits it to the ROM201 as an address pulse.
