ABSTRACT:
In a control apparatus for an internal combustion engine for receiving outputs of a crank angle sensor, air flow sensor, etc., calculating control values from these outputs using a microcomputer to actuate actuators; calculated timings at which the respective actuators are deactuated are compared in advance with each other, the control value for the actuator which should be deactuated earliest is stored in an output compare register, and a deactuation signal for the actuator is generated with count matching of two inputs to a comparator of the output compare register. Thus the respective actuators are sequentially controlled.
