This section provides the AC electrical specifications for the Fast Ethernet controller (FEC). Note that the
timing specifications for the MII signals are independent of system clock frequency (part speed
designation). Furthermore, MII signals use TTL signal levels compatible with devices operating at either
5.0 or 3.3 V.
