Abstract
PURPOSE: To prevent an error interuption process caused by an error signal by enabling a detection circuit to discriminate whether an input interruption signal is a normal interruption signal or error interuption signal due to noises.
CONSTITUTION: The contents of program counter 102 are evacuated to program counter evacuation device 103 by an interruption signal and a period when erasing is possible by an error signal due to noises, etc., is set to the timer. After the time clocking of the timer, AND gate 23 of the detection circuit discriminates whether the input interruption signal is a normal interruption signal or error interruption signal due to noises, etc., in order to prevent an error interruption process, so that the execution process can be performed in accordance with the normal program. The most noticeable point here is that interruption input signal terminal 107 and central processor 104 are connected together via AND gate 23.
