To provide a method for enabling a microprocessor to be restarted after rewriting a program without providing a dedicated circuit and an apparatus using the method, a timer means for counting a predetermined clock is controlled in the following first and second mode, where in the first mode, the timer means is rest (count-cleared) at predetermined intervals by a program so as to monitor an operating status of the program, and in the second mode, the microprocessor is restarted without resetting the timer means at predetermined intervals by the program.
