Ethernet Media Access Controller (EMACV1)
11.1 Introduction
The Ethernet media access controller (EMAC) is IEEE 802.3 compliant supporting 10/100 Ethernet
operation. The EMAC module supports the medium-independent interface (MII) and the MII management
interface (MI). By connecting a physical layer device (PHY) supporting MII, a 10/100 Mbps Ethernet
network is implemented.
11.1.1 Features
• IEEE 802.3 compliant
• Medium-independent interface (MII)
• Full-duplex and half-duplex modes
• Flow control using pause frames
• MII management function
• Address recognition
— Frames with broadcast address are always accepted or always rejected
— Exact match for single 48-bit individual (unicast) address
— Hash (64-bit hash) check of group (multicast) addresses
— Promiscuous mode
• Ethertype filter
• Loopback mode
• Two receive and one transmit Ethernet buffer interfaces
