Abstract

PURPOSE:To avoid an erroneous output of control which is caused when a microprocessor (MPU) has a faulty working, by processing the address, data and writing signals sent from the MPU through a delaying, 1-shot and AND circuits respectively. CONSTITUTION:The address signal A sent from an MPU1 is detected by a detector 2 and then supplied to an AND circuit 4 along with a writing signal D. The data D given from the MPU1 is fetched to a register 3 by the output signal of the circuit 4. An AND5 is secured between the data D and the output of the circuit 4 to produce a signal 9 of period T1. The signal 9 is supplied to a 1-shot circuit 6. The output (b) of the circuit 6 is inverted 7 and supplied to an on-delay circuit 8 having a delay time T2 shorter than the period T1 to obtain a signal (c). An AND9 is secured between the output (d) of the register 3 and the signals (a) and (c) to produce a signal (e). This signal (e) is supplied to an off-delay circuit 10 having a delay time T3 longer than the T1 to produce a signal (g). An AND12 is secured between the signals (g) and (d) to deliver a signal R'. At the same time, the signal (a) is inverted 13 and supplied to an on-delay circuit 11 haing a delay time T3. Then the register 3 is cleared by a delayed signal (h).
