The processor supports a total of six Ethernet interfaces.
The processor supports up to five concurrent external Ethernet interfaces (EPHY ports). Pinmuxing overlaps one of the CPSW3G and PRU_ICSSG1 (PRG1_PRU1).
CPSW3G can be interfaced to the external EPHY using RGMII or RMII. One or two RGMII interfaces can be used. When One of the two external CPSW3G interfaces are used to interface to the EPHY using RMII interfaced the EPHY can be configured as controller (master) or device (slave). When both the CPSW3G external interfaces are used to interface to the EPHY using RMII interface it is recommended to configure the EPHY as device.
