PURPOSE:To facilitate the detection of the presence or absence of the mistaken mounting of hardware parts by deciding the difference between the program count number at the time of timer interruption and the estimated value at the time that the digital device is constituted in the desired manner. CONSTITUTION:When program processing is started, a timer LSI 2 is started and count operation by timer clocks from a timer clock oscillator 3 is started. After a certain time is elapsed, timer interruption signals are produced to a microprocessor (MPU) 1. Upon reception of the timer interruption signal, the program compares in its check routine the program count number and an ID value M (machine type code and the associated value) for the function identification information in the disk device connected to the routine. If machine coincidence M=N, job operating processing is initiated. If M=N, the job drive inhibit processing is initiated. |
