The two-port Gigabit Ethernet MAC (MCU_CPSW0) subsystem provides Ethernet packet communication for the device and is configured in a similar manner as an Ethernet switch.
MCU_CPSW0 features the Reduced Gigabit Media Independent Interface (RGMII), Reduced Media Independent Interface (RMII), and the Management Data Input/Output (MDIO) interface for physical layer device (PHY) management.
The device has integrated two-port Gigabit Ethernet Switch subsystem into device MCU domain named MCU_CPSW0. Table 12-925 shows the MCU_CPSW0 module allocation within device domains.
