W3100A Datasheet, PDF (12/63 Pages) List of Unclassifed Manufacturers – i2Chip W3100A

C1_CR (Channel 1 Command Register) [R/W, 0x01]
This register commands Channel 1 Socket to initialize, connect, close, transmit and receive data.
Sock_Init, Connect, Listen, Close, Send and Recv are used when initializing, establishing a connection,
terminating a connection, sending and receiving data for Channel 1 socket. Each corresponding bit is
automatically cleared after executing the command.
Memory test command is used to verify transmission and reception memory where MCU reads and writes
for the transmission and reception memory. Set memory test bit to ‘1’ to become toggled as ‘0’, ‘1’ and
W3100A acts in memory test mode when in ‘1’. Memory test bit needs to become set at ‘0’ in order for
W3100A to execute normal data transmission and reception.
