PURPOSE: A method for processing a multiple interrupt is provided to process all the interrupts generated from various modules(transistor, decoder, video display processor, etc.). CONSTITUTION: An interrupt processing module(20) has a first status resistor(11) storing a status information of multiple interrupt source, a second status resistor(12) storing a delayed status information as against the status information of multiple interrupt source stored in the first status resistor(11) and a mask resistor(13) controlling a permission/prohibition of insertion. The interrupt processing module(20) compares a status information of the interrupt source stored in the first and the second status resistors(11,12), stores the interrupts to the first status resistors(11) and processes the interrupts.
