中断在系统设计中的应用非常广泛，可以说，硬件中断、软件中断无处不在，在WINCE下驱动开发更是如此，比如：按键中断、触摸屏中断、AUDIO中断、DMA中断.....等等，几乎含概每个模块。因此，了解中断的处理过程对驱动开发极其重要，下面对WINCE下的中断处理过程做一个简单介绍。-Interruption in the system design is very extensive, can be said that the hardware interrupt, software interrupt everywhere, in the driver development, especially under WINCE, for example: interrupt button, touch screen interrupt, AUDIO interrupt, DMA, such as interruption ..... and so on, almost with each module overview. Therefore, the understanding of treatment interruption-driven development process is extremely important, following the interruption of treatment under WINCE process to do a simple introduction.
