ABSTRACT:
A control apparatus and associated method for controlling an internal combustion engine of an automobile. A single chip microcomputer has a memory, which may be a programmable read only memory (PROM), for storing data and is operable in accordance with program data stored in the memory. The data may be stored in the memory after the microcomputer has been mounted on a circuit board. The control apparatus includes the microcomputer with its memory, a control unit for controlling the storing of program data into the memory, a plurality of input terminals for receiving the program data from an external source, and isolation circuitry for isolating the microcomputer during writing of program data into the memory. The microcomputer receives data from external sensors which sense operating conditions of the automobile and applies signals to external actuators to control operating conditions of the engine.
