Abstract
A microcomputer includes a selector group, a priority control circuit and a CPU. The selector group selects an interrupt request signal from among interrupt request signals to be inputted thereto for every priority level in accordance with an input control data. The priority control circuit determines an interrupt request signal having the highest priority level from among the selected interrupt request signals for the priority levels and generating an interrupt signal. The CPU outputs the control data to the selector group and executes an interrupt processing corresponding to the interrupt request signal having the highest priority level.
