Abstract

PURPOSE: To make it possible to utilize a signal an interruption signal having been received once without making it disappear, by generating the interruption signal until a change in input signal is recognized by an arithmetic processing part correctly.
CONSTITUTION: In case that when input signal (a) changes and an interruption signal is generated, arithmetic processing part 15 is in another processing and never accepts the interruption signal, interruption generating circuit 14 keeps on generating interruption signal (d) without making it disappear and immediately after getting ready for the processing of the interruption detecting circuit, arithmetic processing part 15 performs the interruption processing by use of the interruption signal. Namely, since arithmetic processing part 15 when never accepting the interruption signal generates neither input instruction (e) nor output instruction (f), the memory of register 12 is not substituted and comparing circuit 13 keeps on outputting "1".
