| 摘 要： | 本文针对LPC2000系列ARM的向量IRQ中断,分析一般的处理方式,详细研究了可重入中断的特点,提出设计可重入中断处理程序时应使处理器选择转入系统模式,最后通过一个外部中断EINT0嵌套定时器中断TIME0的实例在Proteus仿真平台上验证了方案的正确性。

| Abstract: | For the vectored IRQ interrupt of LPC2000 family of ARM, the general approach is analyzed, a detailed study of the characteristics of reentrant interrupt is discussed and it is put forward that ARM should choose entry system mode when a program of the reentrant interrupt is designed. At last, a sample of the reentrant interrupt design based on Proteus is given, and the correctness of the program is verified. |
