WIZnet Chipset Modes

In this entry, I will explain about the different modes within our chip set. This concept might be hard to understand without a reference model to refer to. That is why I show you this picture
the Bottom Network layers.


Our chipset offers 3 different modes: TCP/UDP Mode, IP Raw Mode, and MAC Raw Mode. Each of these modes represents the different network layer. In MAC RAW mode, the entire Ethernet frame is provided to the MCU without any processing. In IP Raw Mode, the IP datagram is extracted from the Ethernet Frame. In this case, the IP datagram along with the IP header is provided to the MCU. Lastly, in TCP/UDP mode, all the networking headers are removed. You might have expected that TCP/UDP headers are included in the TCP/UDP mode, but actually only the encapsulated data within TCP packets /UDP datagram are provided to the MCU. Most applications use the TCP/UDP mode.

That's it for today. I hope you enjoyed it! Thanks! :)
