Abstract
본 발명은 마이크로 컨트롤의 에물레이터에 있어서, 인터럽트 명령을 이용한 모니터 진입방법에 관한 것으로서,BOI신호의 폴링 엣지에서 어드레스의 싱글스템을 래치하는 단계;상기 래치된 신호를 상기 BOI신호의 라이징 엣지에서 재 래치하여 모니터 인터럽트 인에이블 신호를 만드는 단계;상기 모니터 인터럽트 인에이블 신호에 의해 모니터 인터럽트 명령을 데이터 버스에 실리는 단계;및 상기 데이터 버스에 실린 인더럽트 명령에 의해 모니터 진입단계를 포함한다.The present invention relates to a method for entering a monitor using an interrupt command in an emulator of a micro control, the method comprising: latching a single stem of an address at a falling edge of a BOI signal; relatching the latched signal at a rising edge of the BOI signal Generating a monitor interrupt enable signal; executing a monitor interrupt command on a data bus by the monitor interrupt enable signal; and entering a monitor by an interrupt command loaded on the data bus.
따라서,상술한 바와 같이 본 발명은 모니터 인터럽트 명령을 미리 설정하고,마이크로 컨트롤러가 현재 명령을 수행하고 다음 명령을 실행하기 위한 메모리 읽기 동작을 할 때,데이터 버스에 이 인터럽트 명령을 제공함으로써, 자연스럽게 모니터 모드로 진입할 수 있는 효과를 갖는다.Therefore, as described above, the present invention naturally monitors the interrupt instruction by presetting the interrupt instruction and providing the interrupt instruction to the data bus when the microcontroller performs a memory read operation to execute the current instruction and execute the next instruction. Has the effect of entering the mode.
