The device is compliant with the MII interface specification when VDDMAC is operating at 3.3V. While the MII specification only specifies operation at 3.3V, the device can also support the MII interface at 1.5V, 1.8V, and 2.5V. FIGURE 5-2: MII MAC INTERFACE 5.2.3 RMII MODE The RMII interface supports 10 Mbps and 100 Mbps speeds, and is used as an interface to a RMII-compatible MAC. The device is compliant with the RMII interface specification when VDDMAC is operating at 3.3V. While the RMII spec- ification only specifies operation at 3.3V, the device can also support the RMII interface at 1.5V, 1.8V and 2.5V.
