The interrupt control unit includes: a storage part for storing therein an interrupt control timing table in which a condition of switching a mode of the interrupt control is described; and an interrupt control mode switching part for switching the mode of the interrupt control to the CPU between a permission mode and a mask mode, based on the interrupt control timing table in the storage part.
