This only applies to UDP case(P3-P0 : “0010”)
To use multicasting, write multicast group address and port number to
SOCKET n destination IP and port register respectively before using the
OPEN command.
MAC Filter
0: disable MAC filtering
1: enable MAC filtering
Filters the MAC addresses except own MAC and broadcasting MAC address.
Use No Delayed ACK
0 : Disable No Delayed ACK option
1 : Enable No Delayed ACK option,
This only applies to TCP case (P3-P0 : “0001”)
If this bit is set as ‘1’, ACK packet is immediately transmitted after
receiving data packet from a peer. If this bit is cleared, ACK packet is
transmitted according to internal timeout mechanism.
Multicast
0 : using IGMP version 2
1 : using IGMP version 1
This bit is valid when MULTI bit is enabled and UDP mode is used (P3-P0 :
“0010”).
In addition, multicast can be used to send out the version number in IGMP
messages such as Join/Leave/Report to multicast-group
Reserved
Protocol
Sets up corresponding SOCKET as TCP, UDP, or IP RAW mode
S0_MR_MACRAW and S0_MR_PPPoE are valid only in SOCKET 0.
S0_MR_PPPoE is temporarily used for PPPoE server connection/Termination.
After connection is established, it can be utilized as another protocol.
S0_MR_MACRAW
Sn_MR_CLOSE
Sn_MR_IPRAW
