PROBLEM TO BE SOLVED: To provide an interrupt control method without disturbing an application operation even when the frequency of interrupt factors causing an interrupt event is increased. SOLUTION: The occurrence of an interrupt event is made invalid (step S11) during the execution of an interrupt handler 31 accessed by the reception of the interrupt event, and a start processing task 32 whose execution priority is lower than a normal application is started (step S12). When execution right is transferred to the start processing task 32, a data processing task 33 is started (step S21), and when the execution right is further transferred to the data processing task, the occurrence of the interrupt event is made effective (step S33) after performing data processing about an interrupt factor that causes the interrupt event (step S31).
