1. A method of operating a processor-controlled apparatus for controlling the operation of a combustion engine, said engine including an output shaft driven by mechanical energy converted from heat energy caused by the combustion of a fuel, at least one means controlling energy conversion in response to control signals applied thereto, and engine starting means which includes switching means having first and second states and wherein, during the second state of said switching means, said engine is started by a starter motor, said apparatus being coupled to receive signals produced by sensor means indicative of operating conditions of the engine and including input/output means adapted to receive sensed signals from said sensor means and to deliver control signals to said energy conversion controlling means, said input/output means including first means for generating said control signals in accordance with processor-generated engine control data and second means for producing a starter signal representative of the state of the switching means;

  • said method comprising the steps of;

    (a) detecting a change to the first state from the second state of said switching means in accordance with the starter signal produced by the second means of the input/output means; and

    (b) starting, in accordance with step (a), an operation for detecting the condition of the stopping of energy conversion, so as to return said first means of said input/output means to a prescribed initial condition in response to the termination of energy conversion by said engine.
