MAC和内部PHY之间的MDIO连接疑问

你好，
当MAC内部连接到以太网1000base-X时，我对MDIO配置有疑问。
在pg051-TEMAC用户指南中，有一些关于mdio连接到外部PHY或外部AND内部PHY（两者都在一起）的描述。
但是关于仅连接到内部PHY，没有描述。
Coud你能指导我吗？
下图仅与外部PHY连接，并连接到外部和内部PHY。
谢谢



以下为原文

Hello,
I've a question about MDIO configuration when MAC internally was connected to Ethernet 1000base-X.
In pg051-TEMAC user guide there are some description about mdio connection to external PHY or to external AND Internal PHY(both of them together). But about just connecting to Internal PHY there is no description. Coud you please guide me?
The below images are about just connect to external PHY and connect to external and Internal PHY.
