Abstract
A microcomputer includes an interrupt signal generator for supplying a CPU with an interrupt signal at predetermined time intervals, and a monitoring timer reset by a reset signal generated by the CPU in response to the interrupt signal. An abnormality is sensed on the basis of expiration of time in the monitoring timer. A flag for resetting the monitoring timer during a first processing started by the interrupt signal is stored in a memory device connected to the CPU, and the CPU generates the reset signal in response to the stored flag during a second processing having a priority lower than that of the first processing.
