    RGMII is controlled thru Strap on pin RX_ER. You need to configure it to mode 2 or 3 depending whether AMDIX has to be enabled or disabled.

    RX_ER is PU on reset, please refer to table 9 for appropriate resistors to use. Please make sure the range for each mode is limited and high precision resistors ( 1%) shall be used.
