RMII接口信号定义 RMII接口(Reduced MII接口)是简化的MII接口。它也分为MAC模式和PHY模式。 RMII接口接收、发送和控制的同步参考时钟REF_CLK是由外部时钟源提供的50MHz信号。这与原

某鱼雷声自导的硬件系统使用了百兆网络交换机实现DSP之间的互联。交换机在MAC和PHY之间的接I=I是RMII，但DSP没有相应的外围设备与它匹配。因此必须在FPGA中设计RMII的通讯模块，完成DSP数据格式向RMII

前言在验证打样的板子最后一项主要内容，RMII方式连接的ETH接口。开始网口测试不通，特意封闭了一天，查了一下。还好，硬件没有问题。是软件编程的问题。试验出问题时，手头有开发板好处就来了。找局部电路

PIN17 PIN18应当取 1 1由于是RMII接口，需要给REF_CLK提供50M频率时钟，这里把KSZ8863输出时钟直接接到23脚，再接到单片机PA1软件上，PHY地址应当是3，对应MAC3，该
