Abstract

PURPOSE: To reduce signal lines and also to simplify an analysis of an interruption facior by setting different interruption time to each interruption generating circuit and by leading several interruption factor signal lines to a discrimination circuit through wired OR.
CONSTITUTION: Function blocks 1aW1d with several interruption factors have interruption generating circuits 2aW2d which generate interruption signals on the basis of respective factors and a wired-OR connection between interruption request signal (c) validating an interruption request signal and interruption factor signal line (b) validating an interruption factor signal is made so as to supply a clock signal from clock circuit 14 to interruption generating circuits and interruption discrimination circuit 11; through signal line (d) and signal line (b) is validated as long as the time assigned to each interruption generating circuit by main coutrol part 13 or signal line (e) and discrimination circuit 11 discriminates what inetrruption factor requests the interruption by the clock signal, thereby sending its discrimination result to interruption main control circuit 12.
