4.2.8.4 Ethernet Interface RH850/F1H, F1KM-S4 and F1KH/D8 version only)

Ethernet PHY (IC6) is supplied to provide an external T100Base-TX Ethernet bus interface. The

transceiver can be connected to the microcontroller’s Ethernet interface ETNB via the DIP

switches ETH1 – ETH3.

Please use the following DIP switch configuration to connect the Ethernet transceiver to the

microcontroller:
