Abstract

PURPOSE:To reduce the failure retrieval time of the hardware, by interrupting the processing of information waiting, jumping the processing to an interruption processing routine, taking out and displaying a return address after the completion of the interrupting processing. CONSTITUTION:When a program is looped with the information waiting of the hardware, a microprocessor 2 inputs read-in information to a reset terminal R' of a counter 4 via an AND circuit 5, and counts a pulse from a pulse generator 3 at the counter 4 to detect the time. If consecution of time which is not caused in the normal state is detected, a CO turns on at the output terminal of the counter 4, and an unconditional interruption request signal is given to the device 2 via a NOT circuit 6 to keept the terminal CO. Thus, the device 2 interrupts the processing of information waiting and is jumped to the interruption processing routine. The program address in the vicinity looped for information waiting is displayed 8, the corresponding table is referred to make the failed part of the hardware clear.
