Abstract

PURPOSE:To increase the fail-safe properties, etc., by forcibly resetting a CPU in case when a fault is detected for a microcomputer through a detecting part and switching and selecting the memory storing a stop process program to execute the program through the CPU. CONSTITUTION:When a detecting part 2 detects a fault of a microprocessor CPU1, the part 2 controls a reset line 3 to forcibly reset the CPU1. Thus a selection command 4 is changed from an H level to an L level. The CPU1 restarted by a forcible reset input works based on a program of a memory 11 storing a stop process program and not on a program of a memory M0 that is usually used. The stop process program contains an instruction to stop the present control state after leading the control to a stable state. Thus the CPU1 has a prescribed output action based on the above-mentioned instruction.
