Abstract

PURPOSE:To enlarge a grade of freedom for time establishment by a method wherein selection of establishment times for various timers of a combustion control circuit to which a microcomputer is applied can be made possible depending on existence of connection with a diode in a method of a rectangular diode matrix. CONSTITUTION:This microcomputer 1 in a combustion control circuit issues an output of each time shearing scanning signal for a prepurge timer input read-in and a safety switch timer input read-in from output ports 4 and 5. Then establishment of times corresponding to a prepurge time and a safety switch time respectively is constituted so that it is carried out through input ports 6-9. In this case input ports 6-9 are made to carry special weight of 2sec, 4sec, 8sec and 16sec respectively, and timer time can be made selective freely depending on existence of connection of the timer time establishing diodes 10-17 constituted to obtain a rectangular matrix with these input ports 6-9.
