PURPOSE:To simplify the circuit while keeping the control accuracy of an engine, by giving a weight to a comparison period of each register depending on the accuracy of a pulse signal to be outputted. CONSTITUTION:Timing information of a pulse signal to be outputted is inputted to a register group comprising registers R1, R2-R6, and its output is outputted in time divisin with a multiplexer MPX1. Its output signal is inputted to one terminal of a comparator 7, and an output signal of a counter 6 forming a prescribed time base and a crank angle signal is applied to another terminal. The output signal of the compartor 7 is applied to a latch circuit 8 in time division via a multiplexer MPX2 and a pulse signal is transmitted. In this case, a weight is given to the comparison period of the registers R1, R2-R6 depending on the required accuracy for the pulse signal. |
