Abstract

인터럽트 요구 신호를 발생하는 인터럽트 요구 장치와, 인터럽트 선택신호를 발생하는 제어 신호부와, 상기 제어 신호부에서 출력되는 인터럽트 선택신호를 입력받아 적합한 인터럽트 서비스 루틴을 수행하는 인터럽트 컨트롤러로 이루어지는 것을 특징으로 하는 소프트웨어 제어에 의한 인터럽트 선택회로는 소프트웨어적으로 인터럽트 요구 입력 단자를 선택하므로 시스템이 부팅된 다음에도 다른 인터럽트 요구 장치와 충돌하지 않고 원하는 인터럽트 서비스 루틴을 수행할 수 있다.An interrupt request device for generating an interrupt request signal, a control signal unit for generating an interrupt selection signal, and an interrupt controller for receiving an interrupt selection signal output from the control signal unit and performing an appropriate interrupt service routine; The interrupt selection circuit by software control selects the interrupt request input terminal in software so that the desired interrupt service routine can be performed even after the system is booted without conflict with other interrupt request devices.
