PROBLEM TO BE SOLVED: To provide an interrupt control circuit for determining whether or not there is another masked interrupt request while waiting for permission for the usage of a function necessary for interrupt processing. SOLUTION: The interrupt control circuit 120 for controlling a plurality of interrupt requests in relation to the interrupt processing executed by a processor 110 comprises an interrupt control module unit 150, which is a detection means for determining whether or not there is an interrupt request masked by interrupt processing while executing the interrupt processing, and a priority mask flag 140 for indicating whether or not there is an interrupt request. By this configuration, it is possible to easily determine whether or not there is another masked interrupt request. COPYRIGHT: (C)2008,JPO&INPIT
