PROBLEM TO BE SOLVED: To secure high reliability in order to set the order of processing based on event signals which simultaneously occur from one circuit module to the order of priority by clarifying that those event signals are related to simultaneous occurrence even when the event signals related to the simultaneous occurrence are subsequently accepted due to wiring delay or crosstalk delay.SOLUTION: A simultaneous occurrence flag to be set (changed from a first state to a second state) when a plurality of event signals simultaneously occur from one circuit which synchronously operates is prepared. When it is determined that the event signals related to the simultaneous occurrence have occurred by referring to the simultaneous occurrence flag, processing corresponding to the event signals related to the simultaneous occurrence is executed in the order of priority, or a request for instructing or starting the processing is issued in the order of priority. |
