[0x0000]

This register sets the Source Port number for each Socket when using TCP or UDP mode, and

the set-up needs to be made before executing the OPEN command.

Ex) In case of Socket 0 Port = 5000(0x1388), configure as below,

Sn_DHAR (Socket n Destination Hardware Address Register) [R/W] [0x4006+0x0n00-

0x400B+0x0n00] [0xFFFFFFFFFFFF]

It sets or is set as destination hardware address of Socket n . Also, if SOCKET 0 is used for

PPPoE mode, S0_DHAR sets as PPPoE server hardware an address that is already known.

When using SEND_MAC command at the UDP or IPRAW mode, it sets the destination hardware

address of Socket n . At the TCP, UDP and IPRAW mode, Sn_DHAR is set as destination
