Register Name:
Access Type:
• DATA
For a write operation this is written with the data to be written to the PHY.
After a read operation this contains the data read from the PHY.
• CODE:
Must be written to 10. Reads as written.
• REGA: Register Address
Specifies the register in the PHY to access.
• PHYA: PHY Address
• RW: Read-write
10 is read; 01 is write. Any other value is an invalid PHY management frame
• SOF: Start of frame
Must be written 01 for a valid frame.
