8051 系列芯片通常只有1 个或2 个串口,在工程实际中,往往需要多个串口进行整个系统的通信,但是普通单片机或者DSP 原有的UART 串口都比较少。GM8125可以将1 个全双工的标准串口扩展成5 个全双工的标准串口,并能通过外部引脚控制串口扩展模式:单通道工作模式或多通道工作模式。

CH9329 芯片有 3 串口通信种模式：串口通信模式 0：协议传输模式(默认)；串口通信模式 1：ASCII 模式；串口通信模式 2：透传模式。CH9329 芯片默认工作在串口通信模式 0(协议传输模式),本协议主要用于指定 CH9329 芯片工作在该模式下的串口通信协议。任何模式下，芯片检测到该 SET 引脚为低电平后自动切换到“协议传输模式”，客户端串口设备可进行参数配置。因此，需要进行参数配置时，可以先设置 SET 引脚为低电平，然后再进行配置。
