Abstract: The DS80C400 high-speed microcontroller has a built-in Ethernet media-access controller (MAC) with an industry-standard media independent interface (MII). This application note presents design considerations and fully tested example assembly code for an Ethernet interrupt handler, and code for sending and receiving Ethernet packets. Using these routines, you can develop custom applications such as TCP/IP routers.
