ABSTRACT:
A board wiring fault detection device has an analog-to-digital converter for receiving an optionally set test signal output from a peripheral device, a first memory for storing the test signal, a second memory for storing a predicted data item to be compared to the test signal stored in the first memory, the predicted data item being indicative of a no fault state of a board wiring, and a comparator for comparing test signal to the predicted data item in the first and second memories. The comparator outputs a comparison result to the outside. The peripheral device outputs the test signal upon every release of a reset signal and performs processing.
