Hello okuyama,

You can write MAC address to MAC_ADDR_LOW and MAC_ADDR_HIGH Register.

Supose, your device has MAC ID as, 00:01:F8:00:80:12

So, write 00:01:F8:00 to MAC_ADDR_LOW

and 80:12 to MAC_ADDR_HIGH

Like,

ENET->MAC_ADDR_LOW = (0x00<< 24) | (0xF8<< 16) | (0x01 << 8) | (0x00);

ENET->MAC_ADDR_HIGH = (0x12<< 8) | (0x80);
