and RECEIVE. After W7100A identifies the command, the Sn_CR register is automatically
cleared to 0x00. Even though Sn_CR is cleared to 0x00, the command is still being processed.
To verify whether the command is completed or not, please check the Sn_IR or Sn_SR
registers.
Sn_CR (SOCKET n Command Register)[R/W][0xFE4001 + 0x100n][0x00]
This is used to set the command for SOCKET n such as OPEN, CLOSE, CONNECT, LISTEN, SEND,
CONNECT
Symbol
LISTEN
OPEN
SOCKET n is initialized and opened according to the protocol selected in
Sn_MR (P3:P0). The table below shows the value of Sn_SR corresponding
to Sn_MR
This is valid only in TCP mode (Sn_MR(P3:P0) = Sn_MR_TCP).
In this mode, the SOCKET n is configured as a TCP server which is
waiting for connection-request (SYN packet) from any “TCP CLIENT”.
The
SOCKET_LISTEN.
When a client’s connection request is successfully established, the
Sn_SR changes from SOCK_LISTEN to SOCK_ESTABLIESHED and the
Sn_IR(0) becomes ‘1’. On the other hand, Sn_IR(3) is set as ‘1’ and
Sn_SR changes to SOCK_CLOSED during a connection failure(SYN/ACK
packet failed to transfer)
cf> If the destination port of the TCP Client does not exist during a
connection request, W7100A will transmit a RST packet and Sn_SR is
unchanged.
This mode is only valid in TCP mode and operates the SOCKET n as a
TCP client.
A connect-request (SYN packet) is sent to the TCP server by connecting
to the IP address and port stored in destination address and port
registers (Sn_DIPR0 and Sn_DPORT0)
When a client’s connection request is successfully established, the
