摘要
TL16C752B是TI公司生产的双通道异步收发芯片,该芯片可在通信系统中的实时性要求较高时,用来实现系统的高效多串口通信,从而增强系统的通信接口控制能力,本文介绍了TL16C752B的性能特点及与通信有关的寄存器,给出了用TL16C752B对DSP器件TMS320C6416多串口扩展的硬件框图以及通过TMS320C6416初始化TL16C752B的软件编程,并且使用了CPLD做为片选逻辑控制。
The TLI6C752B is a dual universal asynchronous received transmitter of the TI company, it can be used to realize the multi-serial port communications when the system is in the high need of real-time,then increasing the control ability of the communication port of the system. This paper introduces the characteristics of the TL16C752B and the registers which are relative to the communication, and then renders the hardware circuit which is used by the TL16C752B for extending the TMS320C6416, as well as the program used by the TMS320C6416 to initiate the TL16C752B,Further, the CPLD is used as the chip selector logic controller,
