If (Sn_IR(CON bit) == ‘1’) goto ESTABLISHED stage;
/* In this case, if the interrupt of Socket n is activated, interrupt occurs. Refer to Interrupt
If (Sn_SR == SOCK_ESTABLISHED) goto ESTABLISHED stage;
It initializes the socket n as TCP,
In order to wait for a connection request
If received connection request from remote peer (the stauts of SOCK_SYNRECV), W3150A+ sends ACK
packet and changes to SOCK_ESTABLISHED status. This status can be checked as below.
Register(IR), Interrupt Mask Register (IMR) and Socket n Interrupt Register (Sn_IR). */
