EMAC8_MD_W - Wishbone 8-bit Extended Ethernet Media Access Controller
Figure 1. EMAC8_MD_W - Wishbone 8-bit Extended Ethernet Media Access Controller.
The 8-bit Extended Ethernet Media Access Controller component (EMAC8_MD_W) is a Wishbone-compliant component providing an interface between a processor and a standard Physical Layer device (PHY) through support of the IEEE802.3 Media Independent Interface (MII).
The Controller also enables write/read of the registers internal to the connected PHY device.
Supply of this soft core under the terms and conditions of the Altium End-User License Agreement does not convey nor imply any patent rights to the supplied technologies. Users are cautioned that a license may be required for any use covered by such patent rights.
