Theory of operation
The MMC Ethernet - TCP/IP module contains a 32-bit processor to handle TCP/IP,
PPP (future), and Ethernet protocols. It allows you to use the Ethernet network
architecture and the TCP/IP standard set of protocols to communicate and access
other modules, computers, or the Internet and its resources. The design is based on
the IEEE 802.3 specifications. The data rate is 10 Mbps. The diagram below provides
an overview.
