intrrupt 处理 rtf 文件中通过编程很容易去...... 这是一个基本教程上 LPC214x Mcu 和如何编程他们为那些新到的中断的中断。开始时，先让我们看看： 什么中断、 Irq 和 Isr是。根据 wiki："中断是发送给 CPU 的指示系统事件已发生，需要立即关注的信号"。中断请求，即一个 "IRQ" 可以被认为的特别要求，CPU 要执行一个函数（代码的小片） 当一个中断发生时。此函数或 "小块代码" 技术上称为 "中断服务例程" 或 "ISR"。所以当一个 IRQ 到 CPU 到达时，它停止执行当前的代码并开始执行 ISR后 ISR 执行完毕 CPU 获取回它已停止的位置。
