PURPOSE:To enable to avoid the stopping of operation of the microprocessor, by compulsively outputting the response signal to the callout signal from the microprocessor not connected to the input and output circuit. CONSTITUTION:The microprocessors 1 and 2 and the input and output circuits 3 and 4 are selected with the moving contact 5a of the signal selection circuit 5. Further, when the callout signal is given from the microprocessor not connected to the circuits 3 and 4, the response signal production circuit 6 or 7 outputs the response signal compulsively. Thus, the stopping of the operation of the microprocessor not connected to the circuits 3 and 4 can be prevented. |
