IPC: H03K17/28
Filed: 1989-08-09
Abstract: PURPOSE:To avoid malfunction even when either one is preferentially set between the host timer and a low-order timer by controlling a carry signal from the low-order timer with a carry control circuit when plural timer counters are connected in series. CONSTITUTION:The circuit consists of a low-order timer 1, a host timer 2, a carry control OR gate 3, a reset D flip-flop 4(DFF) of a carry control signal generating circuit generating a signal controlling the OR gate and an OR gate generating the clock of the low-order timer.
