How to read registers of QCA8334 in RBFTC11 media convertor through UART?

Hi!
Tell me please, how to read registers of QCA8334 in RBFTC11 media convertor through UART? In what way I should send data to QCA8334 to read registers?
I didn’t find the uart diagram in datasheet! I found only mdio diagram

Thank You!

Not sure of what you are trying to accomplish. This is very out of scope for this forum, but maybe you will find what och seek in the switch chip datasheet

I was also looking for you, I know that media converters from China on this system configure it with the help of uart commands at I am wondering if you have reached something because this question also puzzles me :wink:
