1、用单次脉冲申请中断，在中断处理程序中使P1.0的输出状态发生反转，并通过发光二极管观察P1.0的电平。
2、通过本实验加深对8051单片机中断系统的理解，学习外部中断的基本使用方法及相关编程。-1 and disrupted by single pulse application in interrupt handlers make P1.0 output state reversals, and by observation of light emitting diode P1.0 level.
2, through this experiment deepened the understanding of 8051 single chip microcomputer interrupt system, learn the basic way of using the external interrupt and related programming
