The subsystem ports depend on the mode of operation. These ports are grouped into interfaces based on their functionality. These interfaces have associated clock and reset ports. The details of the interfaces are given in the following table.
| Interface Name | Description |
|---|---|
| s_axi | AXI4-Lite interface used to configure the AXI Ethernet Subsystem. In processor mode, this interface maps to the AXI Ethernet buffer which configures the TEMAC. In non-processor mode, this interface maps to and directly configures the TEMAC. |
| s_axis_txc | AXI4-Stream Transmit Control. |
| s_axis_txd | AXI4-Stream Transmit Data. |
| m_axis_rxd | AXI4-Stream Receive Data. |
| m_axis_rxs | AXI4-Stream Receive Status. |
| s_axis_tx_av | AXI4-Stream AVB Transmit Data. This interface is present only in AVB mode. |
| m_axis_rx_av | AXI4-Stream AVB Receive Data. This interface is present only in AVB mode. |
| mdio | MDIO interface to configure PHY. This interface is present in MII, GMII, RGMII and SGMII modes. |
| mii | Media Independent Interface. This interface is present only in MII mode. |
| gmii | Gigabit Media Independent Interface. This interface is present only in GMII mode. |
| rgmii | Reduced Gigabit Media Independent Interface. This interface is present only in RGMII mode. |
| sgmii | Serial Gigabit Media Independent Interface. This interface is present only in SGMII mode. |
| sfp | In 1000BASE-X mode, this interface connects to the SFP cage. This interface is present only in 1000BASE-X mode. |
| mgt_clk | Differential clock input for the serial transceiver. This interface is present only in Shared Logic in Subsystem configuration in SGMII or 1000BASE-X modes. |
