| 13 | The Gigabit Media Independent Interface (GMII) to Reduced Gigabit Media |
| 14 | Independent Interface (RGMII) core provides the RGMII between RGMII-compliant |
| 15 | ethernet physical media devices (PHY) and the Gigabit Ethernet controller. |
| 16 | This core can be used in all three modes of operation(10/100/1000 Mb/s). |
| 17 | The Management Data Input/Output (MDIO) interface is used to configure the |
| 18 | speed of operation. This core can switch dynamically between the three |
| 19 | different speed modes by configuring the converter register through mdio write. |
| 20 | The core cannot function without an external phy connected to it. |
