单片机微控制器中断处理算法改进

An improved Algorithm for Interrupt Handling of SCM Microcontroller

以LPC2132微控制器电源控制电路为例,分析了使用该微控制器进行中断处理算法遇到的中断嵌套及伪中断等问题,并根据LPC2132微控制器中断性能的特点,提出了具有针对性的有效简易改进算法,为微控制器中断处理算法设计提供了参考。

This paper analyses the shortcomings and the problem of the interrupt handling algorithm of SCM with the control circuit using LPC2132 SCM （single chip microcomputer） as MCU as an example. An improved algo- rithm is proposed to solve the shortcomings, which provides reference for the design of interrupt handling algorithm of SCM.
