MACRAW

MACRAW Mode supports Data Communication in Ethernet MAC and it is only using SOCKET 0.

MACRAW Mode SOCKET 0 receives all Ethernet Packet or receiving Ethernet Packet (as

Broadcast, Multicast and a Data Packet having the same Destination MAC Address with SHAR) is

restricted by Sn_MR [MR]. And also Sn_MR2 can block receiving Broadcast, Multicast and IPv6

Packet.

MACRAW Mode SOCKET 0 does not receive any Data Packet for other SOCKET but it receives

ARP Request and PING Request (If IPRAW Mode SOCKET does not support ICMP). Even though

MACRAW Mode SOCKET 0 receives ARP and PING Request, W5100S transmits automatically ARP

and PING Reply.

Figure 12 shows MACRAW Mode SOCKET 0 Operation Flow.
