T
compatible Ethernet interface. Two modules comprise the Ethernet interface: the
Ethernet front-end (EFE) and the media access controller (MAC).
The MAC module interfaces to an external physical layer (PHY) device using the
media independent interface (MII) standard defined by IEEE 802.3u. The MAC
interface includes the MII clock and data signals.
