Chapter 17
Fast Ethernet Controller (FEC)
17.1
This chapter provides a feature-set overview, a functional block diagram, and transceiver connection
information for the 10 and 100 Mbps MII (media independent interface), as well as the 7-wire serial
interface. Additionally, detailed descriptions of operation and the programming model are included.
17.1.1
The Ethernet media access controller (MAC) supports 10 and 100 Mbps Ethernet/IEEE 802.3 networks.
An external transceiver interface and transceiver function are required to complete the interface to the
media. The FEC supports three different standard MAC-PHY (physical) interfaces for connection to an
external Ethernet transceiver. The FEC supports the 10/100 Mbps MII and the 10 Mbps-only 7-wire
interface.
