|Configuring the PHY speed.||Upon reset, all ports are set to 10G. To change the PHY speed, set the PHY memory map to change to other modes: 10G SerDes Framer Interface (SFI), or 1G1000Base-X.|
|Changing the speed between 1 Gbps and 10Gbps in 1000BASE-X.||Write one of the following values to the PHY's register at address offset 0x12C0.
To set port 0 to 1000BASE-X: write_32 0x02_52C0 0x11
To set port 0 to auto-detection mode: write_32 0x02_52C0 0x01
