ABSTRACT:
A control apparatus for an internal combustion engine includes pulse converter blocks each comprising a register, a detection circuit for determining if the information content of the register has met a predetermined condition and an increment/decrement circuit for incrementing or decrementing the information content of the register. A block is provided for each of the output signals from a CPU, and the pulse converter blocks are driven by a common clock pulse so that the counting operations and the condition detecting operations of the blocks are effected in synchronism with the common clock pulse.
