mode, not only can it use the SOCKET1~7 in the ‘Hardwired TCP/IP stack’, but it can also be
used as a NIC (Network Interface Controller). Therefore, any SOCKET1~7 can be used with
‘Software TCP/IP stack’. Since the W7100A supports ‘Hardwired TCP/IP stack’ and ‘Software
TCP/IP stack’, it calls ‘Hybrid TCP/IP stack’. If user wants more SOCKETs beyond the
supported 8 SOCKETS, the SOCKET in which the user wants high performance should be
utilizing the ‘‘Hardwired TCP/IP stack’, and the others should be using ‘Software TCP/IP
stack’ by MACRAW mode. So it overcomes the limited capacity of 8 SOCKETS. The SOCKET of
MACRAW mode can process all protocols except using in SOCKET1~7. Since the MACRAW
communication is pure Ethernet packet communication (there is no other processing), the
MACRAW designer should use the ‘Software TCP/IP stack’ to process the protocol. The
