Abstract
An interruption control apparatus includes registers storing priority data and a circuit producing scanning data in a priority order. The priority data is compared with the scanning data by a scanning operation. If the priority data is equal to the scanning data, a coincidence signal is generated. An interruption request signal from an interruption source is transferred to an interruption processing unit only when the coincidence signal is being generated. Thus, a priority control for a plurality of interruption requests can be performed by using a simple hardware circuit without complex software processing.
