
and execute ‘OPEN’ command. If the Sn_SR is changed to SOCK_IPRAW after the ‘OPEN’
command, the SOCKET initialization is completed.


IPRAW data is as below.
Select the SOCKET and set the protocol number. Then set the Sn_MR(P3:P0) to IPRAW mode
Refer to the section 9.2.2.1 ‘Unicast & Broadcast’.
Process the IPRAW data which is received in internal RX memory. The structure of received
/* wait until Sn_SR is changed to SOCK_IPRAW */
/* sets Protocol number, the protocol number is used in Protocol Field of IP Header. */
Sn_PROTO = protocol_num;
/* sets IP raw mode */
Sn_MR = 0x03;
/* sets OPEN command */
Sn_CR = OPEN;
if (Sn_SR != SOCK_IPRAW) Sn_CR = CLOSE; goto START;
