In this state, the SOCKET n is opened in TCP mode and
initialized the first step of TCP connection establishment.
Now, the user can use the LISTEN and CONNECT commands.
When Sn_MR(P3:P0) is Sn_MR_TCP and the OPEN command is
used, the stage changes to SOCK_INIT.
SOCKET n operates in TCP Server Mode and waits for a
connection-request (SYN packet) from a “TCP CLIENT”.
When the LISTEN command is used, the stage changes to
SOCK_LISTEN
Once the connection is established, the SOCKET state
changes from SOCK_LISTEN to SOCK_ESTABLISHED;however,
if the connection fails, TCP
and the state changes to SOCK_CLOSED.
changes from the SOCK_LISTEN or CONNECTS state to the
SOCK_ESTABLISHED state. At this stage, DATA packets can be
exchanged by using the SEND or RECV command.
In this case, a disconnect-request (FIN packet) is received
from a peer. Although the TCP connection is half-closed,
data packet can still be transferred. In order to complete
the TCP disconnection, the DISCON command should be
used. When a socket is closed without going through the
disconnection-process, the CLOSE command should be used.
The socket is opened in UDP mode. The SOCKET status is
changed to SOCK_UDP when Sn_MR(P3:P0) is Sn_MR_UDP
and OPEN command is used. Unlike TCP mode, the SOCKET
in UDP mode can transfer data without establishing a
connection (3 way handshake)
The socket is opened in IPRAW mode. The SOCKET status is
change to SOCK_IPRAW when Sn_MR(P3:P0) is Sn_MR_IPRAW
and OPEN command is used. IP Packet can be transferred
without a connection similar to the UDP mode.
SOCKET0 is opened in MACRAW mode. The SOCKET status is
change
S0_MR_MACRAW and S0_CR = OPEN. MAC packet(Ethernet
frame) can be transferred similar to UDP mode.
SOCKET 0 is opened in PPPoE mode. The SOCKET status is
