The I/O interface is routed to the MIO for RGMII, and to the EMIO for GMII/MII connectivity. The PL can modify the GMII/MII interface from the MAC to construct other Ethernet interfaces that connect to external devices via PL pins. The routing of the Ethernet communications signals are shown in This Figure. The Ethernet communications ports are independently routed to the MIO pins (as RGMII) or to a set of EMIO interface signals (as GMII). When using the EMIO interface, both the TX and RX clocks are inputs to the PS.
