Sn_DPORTR (SOCKETn Destination Port Register) [WO]

[0x08212+0x40n/0x212+0x40n] [0x0000]

It sets as destination port number of SOCKETn. If SOCKET0 is used as PPPoE mode,

S0_DPORTR sets PPP session ID that is already known.

It is valid only in TCP, UDP or PPPoE mode, and ignored in other modes.

At the TCP mode, when operating as "TCP CLIENT" it sets as the listen port number of "TCP

SERVER" before performing CONNECT command.

At the UDP mode, Sn_DPORTR sets as the destination port number to be used for transmitting

UDP DATA packet before performing SEND or SEND_MAC command.

At the PPPoE mode, S0_DPORTR sets as PPP session ID that is already known. PPP session

ID (set by S0_DPORTR) is applied to PSIDR after performing OPEN command.

Ex) Sn_DPORTR = 5000(0x1388)

Sn_DIPR (SOCKETn Destination IP Address Register) [R/W]

[0x08214+0x40n/0x214+0x40n] [00.00.00.00]

It sets or is set as destination IP address of SOCKETn. If SOCKET0 is used as PPPoE mode,

S0_DIPR sets PPPoE server IP address that is already known.

It is valid only in TCP, UDP, IPRAW or PPPoE mode, but ignored in MACRAW mode.

At the TCP mode, when operating as "TCP CLIENT" it sets as IP address of "TCP SERVER"

before performing CONNECT command and when operating as "TCP SERVER", it is internally

set as IP address of "TCP CLIENT" after successfully establishing connection.

At the UDP or IPRAW mode, Sn_DIPR sets as destination IP address to be used for

transmitting UDP or IPRAW DATA packet before performing SEND or SEND_MAC command.

At the PPPoE mode, S0_DIPR sets as PPPoE server IP address that is already known.

Ex) Sn_DIPR = 192.168.0.11
