The three-port switch (CPSW) Ethernet Subsystem has one 10/100/1000 Ethernet port with selectable RMII, RGMII, and MII interfaces.
The interface modes for all 2 Ethernet ports are selected by configuring the Ethernet interface mode selection bitfield (PORT_MODE_SEL) in the CTRLMMR_ENET1_CTRL and CTRLMMR_ENET2_CTRL registers.
See the device-specific Datasheet for configuring the pin mux mode as per the interface selected.
