Abstract

PURPOSE:To shorten the interruption time of operation when a fault is occurring, by releasing an inhibiting circuit when the inhibition time of a reset signal exceeds a normal time, in an information processor which is initialized with a reset signal from another device. CONSTITUTION:A reset signal 10 from a different device is held in a register 1 temporarily and unless a resetting inhibiting register 2 is set, the reset signal 15 is made effective with a signal 17 to initialize a device with a signal 13. When the resistor 2 is set, the signal 15 held in the register 1 is inhibited with the signal 17 and a resetting inhibiting timer 3 is started. Normally, a processor finishes processing in a resetting inhibition state and the register 1 and timer 3 are reset. Even if the inhibiting register is not released a certain time later, the inhibiting register 2 is reset by a gate 6 with the time-up signal 14 of the timer, so the signal 13 operates to initialize the device.
