Abstract

PURPOSE:To eliminate the malfunction and to know an accurate time of execution, by detecting that the execution of a program is set in a prescribed state and controlling the working of a counter circuit by the detection signal. CONSTITUTION:A microcomputer includes a central processing mechanism CPU6, a monitor interruption terminal 5 to which the signal indicating to shift the control panel of the CPU6 to a control program from a user program is supplied, a flip-flop 7 which is controlled by the CPU6, a timer 4 which has a timing or counting operation, and a timer control part 8. When it is desired to confirm the internal state of the microcomputer, an indication signal is supplied to the terminal 5. Then the CPU6 delivers a control signal 61 to set the flip- flop 7. A count stop indication is given to the part 8 by an output signal 71 of the flip-flop 7.
