Sn_DHAR (Socket n Destination Hardware Address Register) [R/W] [0x0406–0x040B, 0x0506–0x050B,
0x0606–0x060B, 0x0706–0x070B] [0x00]
This Register sets the Destination Hardware address of each Socket.
Ex) In case of Socket 0 Hardware address = 08.DC.00.01.02.10, configuration is as below,
0x0406
0x0407
0x0408
0x0409
0x040A
0x040B
0x08
0xDC
0x00
0x01
0x02
0x0A
Sn_DIPR (Socket n Destination IP Address Register) [R/W] [0x040C–0x040F, 0x050C–0x050F, 0x060C–
0x060F, 0x070C–0x070F] [0x00]
This Register sets the Destination IP Address of each Socket to be used in setting the TCP connection. In
active mode, IP address needs to be set before executing the Connect command. In passive mode, W3150
sets up the connection and then updates with peer IP internally.
Ex) In case of Socket 0 Destination IP address = 192.168.0.11, configure as below.
0x040C
0x040D
0x040E
0x040F
192 (0xC0)
168 (0xA8)
0 (0x00)
11 (0x0B)
Sn_DPORT (Socket n Destination Port Register) [R/W] [0x0410–0x0411, 0x0510–0x0511, 0x0610–
0x0611, 0x0710–0x0711] [0x00]
This Register sets the Destination Port number of each Socket to be used in setting the TCP connection. In
active mode, port number needs to be set before executing the Connect command. In passive mode,
W3150 sets up the connection and then updates with peer port number internally.
Ex) In case of Socket 0 Destination Port = 5000(0x1388), configure as below,
0x0410
0x0411
0x13
0x88
Sn_MSS (Socket n Maximum Segment Size Register) [R/W] [0x0412-0x0413, 0x0512-0x0513, 0x0612-
0x0613, 0x0712-0x0713] [0x00]
This Register is used for MSS (Maximum Segment Size) of TCP, and the Register displays MSS set by the
other party when TCP is activated in Passive Mode.
Ex) In case of Socket 0 MSS = 1460(0x05B4), configure as below,
0x0412
0x0413
0x05
0xB4
