The ENET is designed to support both 10- and 100-Mbps Ethernet networks compliant with IEEE 802.3.
An external transceiver interface and transceiver function are required to complete the interface to the
media. The ENET supports 10/100-Mbps MII (18 pins altogether), 10/100-Mbps RMII (10 pins, including
serial management interface), for connection to an external Ethernet transceiver. All signals are compatible
with transceivers operating at a voltage of 3.3 V.
The following subsections describe the timing for MII and RMII modes.
