layers. The IPRAW supports IP layer protocol such as ICMP (0x01) and IGMP (0x02) according to
the protocol number. The ‘ping’ of ICMP or IGMP v1/v2 is already included in W7100A by
hardware logic. But if the user needs, the host can directly process the IPRAW by opening the
SOCKET n to IPRAW. In the case of using IPRAW mode, user must set the protocol number field
of the IP header to what the user wants to use. The protocol number is defined by IANA. Refer

does not support TCP (0x06) or UDP (0x11) protocol number. The SOCKET communication of
IPRAW mode only allows the communication of an assigned protocol number. The ICMP
SOCKET cannot receive unassigned protocol data except assigned protocol data such as IGMP.
Since the host manages all protocol process for data communication, the timeout cannot
