UDP provides unreliable and connectionless datagram transmission structure. It processes data without
connection establishment. Therefore, UDP message can be lost, overlapped or reversed. As packets can
arrive faster, recipient can not process all of them. In this case, user application should guarantee the
reliability of data transmission. UDP transmission can be processed as below,
{
START:
}
/* sets UDP mode */
Sn_MR = 0x02;
/* sets source port number */
Sn_PORT = source_port;
/* sets OPEN command */
Sn_CR = OPEN;
/* Check if the value of Socket n Status Register(Sn_SR) is SOCK_UDP. */
if (Sn_SR != SOCK_UDP) Sn_CR = CLOSE; goto START;
/* ※ The value of Source Port can be appropriately delivered when remote HOST knows it. */
Initialize the socket n as UDP.
