5.9 Ethernet
When running any Ethernet software, a unique MAC address should be used. A unique Renesas allocated MAC
address is attached to the RSK+RX62N PCB as a sticker, and should be always be used with this device ensured to
ensure full compatibility when using other Renesas hardware on a common Ethernet connection.
An Ethernet controller IC is fitted to the RSK, and is connected to the Ethernet MCU peripheral. The RX62N MCU
supports full duplex 10Mb/s and 100Mb/s transmission and reception. The Ethernet status LEDs (LED6 – 9) are
detailed in §5.4. The connections for the Ethernet controller are listed in Table 5-7 below.
