Abstract

PURPOSE: To simplify an interruption process by giving an address word meaning equivalent to one of interruption causes and executing the process by judging the interruption cause when a data processor read the interruption address word.
CONSTITUTION: When data from data processor 1 is transferred to terminal equipment 3 or data from terminal equipment 3 is transferred to processor 1, either data is transferred via data transfer control circuit 2. Then, control circuit 2 in this constitution is equipped with interruption circuit 13 and interruption address generating circuit 14. The address word of circuit 14 is given interruption cause number IS which corresponds to an interruption cause and a meaning equivalent to the interruption cause before being sent out. Then, unit 1 or 3 having been interrupted judges the corresponding cause from interruption cause number IS on receiving the address of the interruption address word, thereby executing the corresponding process.
