摘要
PXA255微处理器的同步串行控制器(SSPC)是一个全双工、同步串行通信接口控制器,它可以方便地与具有串行通信协议的外设直接相连,用于在短距离与外设之间传送控制/状态信息和输入/输出数据。文中详细介绍PXA255同步串行控制器所支持的串行通信协议格式、寄存器结构及接口原理,以具体实例介绍PXA255同步控制器在实际开发中应用。
The synchronous serial port controller （SSPC） in the PXA255 processor is a full-duplex synchronous serial communication interface controller. It can directly connect to external peripherals that use serial synchronous protocols conveniently for transferring the control and status information and input/ output data in short distance. The format of serial communication protocols that SSPC supports and its registers structure and the principle of interface are introduced. The application of SSPC in development is also introduced by example.
