It is used to initialize the socket. According to the value of Socket n Mode Register
(Sn_MR), Socket n Status Register(Sn_SR) value is changed to SOCK_INIT,
SOCK_UDP, SOCK_IPRAW, or SOCK_MACRAW.
For more detail, refer to 5. Functional Description.
It is only used in TCP mode.
It changes the value of Socket n Status Register (Sn_SR) to SOCK_LISTEN in order
to wait for a connection request from any remote peer (TCP Client).
For more detail, refer to 5.2.1.1. SERVER.
It is only used in TCP mode.
It sends a connection request to remote peer(TCP SERVER). If the connection is
failed, Timeout interrupt will occur.
For more detail, refer to 5.2.1.2. CLIENT.
It is only used in TCP mode.
It sends a connection termination request. If connection termination is failed,
Timeout interrupt will occur. For more detail, refer to 5.2.1.1. SERVER.
* In case of using CLOSE command instead of DISCON, only the value of Socket n
Status Register(Sn_SR) is changed to SOCK_CLOSED without the connection
termination process.
