Some of the inter-integrated circuit (I2C) controllers can be used either for the EMAC or for general I2C communication, as listed in the table above. Using an I2C controller for Ethernet provides flexibility for the EMACs to use Management Data Input/Output (MDIO) or I2C for PHY communication. The remaining I2C controllers are available for general I2C communication.
