As connection is established, data transmission and receipt can be performed.
/* sets OPEN command */
Sn_CR = OPEN;
if (Sn_SR != SOCK_INIT) Sn_CR = CLOSE; goto START;
/* listen socket */
Sn_CR = LISTEN;
if (Sn_SR != SOCK_LISTEN) Sn_CR = CLOSE; goto START;
If (Sn_IR(CON bit) == „1‟) goto ESTABLISHED stage;
/* In this case, if the interrupt of Socket n is activated, interrupt occurs. Refer to
If (Sn_SR == SOCK_ESTABLISHED) goto ESTABLISHED stage;

Set the LISTEN command to the command register. The related register is below.
Socket n Command Register (Sn_CR)

If connection request is received from remote peer (the status of SOCK_SYNRECV), W5100
sends ACK packet and changes to SOCK_ESTABLISHED status. This status can be checked
as below.
Interrupt Register(IR), Interrupt Mask Register (IMR) and Socket n Interrupt Register
(Sn_IR). */
