Abstract

PURPOSE:To enable to detect malfunction due to external disturbance with low cost, by setting an address not accessed with a normal operation in the address of a storage device and an input/output device and detecting an address signal corresponding to the address. CONSTITUTION:At least one address not accessed normally is set to a memory array 12 and an input/output device 13 in advance, and a gate circuit 18 inputting malfunction signals phia phib, phic and phid from the corresponding address selecting lines, e.g., M3, M6, N3 and N6 is provided, and a detection signal phis outputted from it is supplied as a reset signal of a CPU11. When at least one signal such as address designation signals phia, phib, phic and phid is generated from at least one of the selection lines M3, N6, N3 and N6, the malfunction of a data processor can be detected by detecting the output signal phis of the gate circuit 18.
