PURPOSE:To form a precise brake signal with a simple constitution by providing the titled device with a memory which is simultaneously selected in accordance with a memory access from a computer system developing the system. CONSTITUTION:The brake memory BM to be simultaneously selected in accordance with a memory access from the computer system developing the system is prepared. The contents of the brake memory BM are successively read out in accordance with the execution of a program. The brake memory BM supplies a brake signal allowing the execution to be continued if the read-out signal is ''0'' or stopping the execution if ''1'' to a brake control circuit BC. Receiving the brake signal, the brake control circuit BC stops the execution of the program in the microprocessor MCU.
