DM9051（最新SPI接口网络芯片相关资料）

侨峰之我行

DM9051NP SPI介面网卡芯片是为了方便MCU单片机系统进行乙太网通信而开发出的解决方案。DM9051NP晶片是带有行业标准串列外设介面（Serial Peripheral Interface，SPI）的独立乙太网控制器。DM9051NP符合IEEE 802.3 规范，它还支援以DMA 模式來传输，以实现资料传送快速。DM9051NP通过1个中断引脚和SPI介面來进行与主控制器/MCU单片机的通信，资料传输规格为10/100 M。

有人遇到过STM32驱动DM9051的过程出现的问题嘛，就是SPI什么的都通信正常，ID和每个寄存器的值都能正常读取出来，但是PHY层感觉总是有些问题，网线插上去也没办法识别，排查过网线确实没有问题。这个是打印的寄存器的值：
补充，这个是我打印出来的MAC和PHY层寄存器的值VIDL: 0x46
