Sn_MSSR and retry the communication with the OPEN command.
is valid only in IPRAW mode, and ignored in other modes. Sn_PROTO is set before OPEN
command. When SOCKET n is opened in IPRAW mode, it transmits and receives the data of the
protocol number set in Sn_PROTO. Sn_PROTO can be assigned in the range of 0x00 ~ 0xFF, but
W7100A does not support TCP(0x06) and UDP(0x11) protocol number

configurable in the size of 1, 2, 4, 8, 16Kbytes. 2Kbytes is assigned when reset.
Sn_RXMEM_SIZE
Sn_PROTO (SOCKET n Protocol Number Register)[R/W][0xFE4014 + 0x100n][0x00]
It is a 1 byte register that sets the protocol number field of the IP header at the IP layer. It
Protocol number is defined in IANA(Internet assigned numbers authority). For the detail,
Sn_TOS (SOCKET n TOS Register)[R/W][0xFE4015 + 0x100n][0x00]
It sets the TOS(Type of Service) field of the IP header at the IP layer. It should be set before
Sn_TTL (SOCKET n TTL Register)[R/W][0xFE4016 + 0x100n][0x80]
It sets the TTL(Time To Live) field of the IP header at the IP layer. It should be set before
Sn_RXMEM_SIZE
It configures the internal RX Memory size of each SOCKET. RX Memory size of each SOCKET is
Ex) In case of SOCKET 0 MSS = 1460(0x05B4), configure as below,
Ex) Internet Control Message Protocol(ICMP) = 0x01, Internet Group Management Pr
