8.14.1 MII Mode Options
The Ethernet interface can be configured for MII operation by setting the hardware pin RMIIMIIS low. The MII
interface consists of 17 pins. For instructions on clocking the Ethernet Interface while in MII mode, see
Section 8.3. Diagrams of system connections for MII operation are shown in Figure 8-5 and Figure 8-6.
8.14.2 RMII Mode
The Ethernet interface can be configured for RMII operation by setting the hardware pin RMIIMIIS high. RMII
interface operates synchronously from the external 50 MHz reference (REF_CLK). Only 7 signals are required.
The following figure shows the RMII architecture. Note that DCE mode is not supported for RMII mode and RMII
is valid only for full duplex operation.
