Overview

IPRAW is the type of data communication that uses IP layer, which is the lower protocol layer of UDP and TCP.

W5500 is embedded a Hardwired TCP/IP that is structured from Link layer to Transport later, excluding the Application Layer in OSI 4 layers.
The W5500 supports IPRAW mode for data processing in IP layer protocols like ICMP (0x01) and IGMP (0x02) according to the protocol number. But if user needs, the host can directly process the IPRAW by opening the SOCKET n to IPRAW. This application note described ICMP, one of the IP Layer’s protocol, and how it is used as a simple Ping application.
