摘要
本文论述了基于嵌入式系统的某项目在联试过程中,由于多个外部中断源共用一路向MCU申请中断,会出现MCU软件对外部中断源漏响应异常。本文分析了多个外部中断源共用一路向MCU申请中断的情况下,漏中断产生的原因及机理,并给出了相应的解决方案。
MCU software based on embedded system will leak respond exception because of many interrupted source request interruption use one route.This paper analyzes the reason and mechanism of leaked respond and gives the resolve way.
