ABSTRACT:
A control apparatus and associated method for controlling a single chip microcomputer which has a memory for storing data. The microcomputer is operable in accordance with program data stored in the memory, which may be a programmable read only memory (PROM). The data may be stored in the memory after the microcomputer has been mounted on a circuit board. The control apparatus includes the programmable 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 control apparatus may be used for controlling an internal combustion engine of an automobile.
