0x00

SOCK_CLOSED

It is shown in case that CLOSE commands are given to

Sn_CR, and Timeout interrupt is asserted or connection is

terminated. In this SOCK_CLOSED status, no operation

occurs and all resources for the connection is released.

0x13

SOCK_INIT

It is shown in case that Sn_MR is set as TCP and OPEN

commands are given to Sn_CR. This is the initial step for

TCP connection establishment of a socket. In this SOCK_INIT

status, the command type (LISTEN or CONNECT) of Sn_CR

will decide the operation type – TCP server mode or Client

mode.

0x14

SOCK_LISTEN

It is shown in case that LISTEN commands are given to

Sn_CR at the SOCK_INIT status. The related socket will

operate as TCP Server mode, and become ESTBLISHED status

if connection request is normally received.

0x17

SOCK_ESTABLISHED

It is shown in case that connection is established. In this

status, TCP data is transmitted and received.

0x1C

SOCK_CLOSE_WAIT

It is shown in case that connection termination request is

received from peer host. At this status, the Acknowledge

message has been received from the peer, but not

disconnected. The connection can be closed by receiving

the DICON or CLOSE commands.

0x22

SOCK_UDP

It is shown in case that OPEN commands are given to Sn_CR

when Sn_MR is set as UDP. As this status does not need the

connection process with peer, the data can be directly

transmitted and received.

0x32

SOCK_IPRAW

It is shown in case that OPEN commands are given to Sn_CR

when Sn_MR is set as IPRAW. At the IPRAW status, the

following protocols of IP Header are not processed. Refer to

“IP RAW” for more information.

0x42

SOCK_MACRAW

It is shown in case that OPEN commands are given to S0_CR

when S0_MR is set as MACRAW.

At the MAC RAW status, there is no protocol process for a

packet. For more information, refer to “MAC RAW”.

0x5F

SOCK_PPPOE

It is shown in case that OPEN commands are given to S0_CR

when S0_MR is set as PPPoE.
