    Hi,

    MDC/MDIO interface is IEEE defined standard interface. Protocol information is part of the datasheet. For evaluation assitance,  TI offers USB-MDIO tool to interface with MDC/MDIO of DP83869HM. 

    Please refer to below link for more details.

    BTW, for Media Convertor Mode, basic functionality shall work with HW straps and will not need MDIO config.

    Regards,
