    Hi,


    As I understand it, you have some inquiries related to the Master CGB PMA interface width reconfiguration. For your information, as I understand it from the A10 XCVR PHY user guide, it seems like the master CGB reconfiguration is not supported. I have also crossed check with ATX PLL Reconfiguration Profiles and verified that this MCGB PMA interface width must be the same for different profiles. Sorry for the inconvenience.


    You might need to look into non-bonded mode if you would like to perform the PMA interface width reconfiguration.


    Please let me know if there is any concern. Thank you.



    Best regards,
