It is set as ‘1’ if send operation is completed.
It is set as ‘1’ if Timeout occurs during connection establishment or termination
and data transmission.
It is set as ‘1’ whenever w3150a+ receives data.
It is used to close the socket. It changes the value of Socket n Status
Register(Sn_SR) to SOCK_CLOSED.
It transmits the data as much as the increased size of Socket n TX Write Pointer.
For more detail, refert to Socket n TX Free Size Register (Sn_TX_FSR), Socket n TX
Write
Register(Sn_TX_RR) or 5.2.1.1. SERVER.
It is used in UDP mode.
The basic operation is same as SEND. Normally SEND operation needs Destination
Hardware Address that is received in ARP(Address Resolution Protocol) process.
SEND_MAC uses Socket n Destination Hardware Address(Sn_DHAR) that is written
by users without ARP process.
It is only used in TCP mode.
It checks the connection status by sending 1byte data. If the connection is already
terminated or peer has no response, Timeout interrupt will occur.
Receiving is processed with the value of Socket n RX Read Pointer
Register(Sn_RX_RD).
For more detail, refer to
Received
Register(Sn_RX_WR), and Socket n RX Read Pointer Register(Sn_RX_RD)
