0x22 SOCK_UDP
0x32 SOCK_IPRAW
In case that OPEN commands are given to Sn_CR when Sn_MR is set as
UDP.
In case that OPEN commands are given to Sn_CR when Sn_MR is set as
IPRAW.
Below is shown in the status change, and does not need much attention.

Description
0x15 SOCK_SYNSENT
It is shown in case that CONNECT commands are given to Socket n
Command Register(Sn_CR) at the SOCK_INIT status. It is automatically
changed to SOCK_ESTABLISH when the connection is established.
0x16 SOCK_SYNRECV
It is shown in case that connection request is received from remote
peer(CLIENT). It normally responds to the requests and changes to
SOCK_ESTABLISH.
0x18 SOCK_FIN_WAIT1
0x19 SOCK_FIN_WAIT2
It is shown in the process of connection termination. If the termination is
0x1A SOCK_CLOSING
normally processed or Timeout interrupt is asserted then automatically
0X1B SOCK_TIME_WAIT
changed to SOCK_CLOSED.
0X1D SOCK_LAST_ACK
0x11 SOCK_ARP
It is shown when ARP Request is sent in order to acquire Hardware
0x21
Address of remote peer when it sends connection request in TCP mode
0x31
or sends data in UDP mode. If ARP Reply is received, it changes to the
status, SOCK_SYNSENT, SOCK_UDP or SOCK_ICMP, for next
operation.
Sn_PORT (Socket n Source Port Register) [R/W] [0x0404–0x0405, 0x0504–0x0505, 0x0604–0x0605,
0x0704–0x0705] [0x00]
This Register sets the Source Port number for each Socket when using TCP or UDP mode, and the set-up
needs to be made before executing the OPEN Command.
Ex) In case of Socket 0 Port = 5000(0x1388), configure as below,
0x0404
0x0405
0x13
0x88
