中断在MCU里面应用是非常广泛的，比如应用在时钟上的按键，我们可以发现基本上是不怎么使用的，如果用中断方式来代替传统的扫描方式，能节省CPU资源。也就是具有良好的实时性，本节将讲述CC2530的中断应用。-Interrupt inside MCU applications is very broad, such as the application buttons on the clock, we can find that is basically not very used, interrupt instead of the traditional way of scanning, saving CPU resources. That is has a good real-time performance, this section will describe the CC2530 interrupt the application.
