The three-port gigabit ethernet switch subsystem (GMAC_SW) provides ethernet packet communication and can be configured as an ethernet switch. It provides the gigabit media independent interface (G/MII) in MII mode, reduced gigabit media independent interface (RGMII), reduced media independent interface (RMII), and the management data input output (MDIO) for physical layer device (PHY) management.
Figure 24-186 shows the GMAC_SW subsystem overview.
