Example Register Offset Value
Multicast DestID 0x01 to ports 4, 5, 6, and 7 on
all ports using multicast mask 0x27. Multicast Mask Port CSR 0x80 0x00270410
0x00270510
0x00270610
0x00270710
Multicast Association Selection CSR 0x84 0x00010027
Multicast Association Operations CSR 0x88 0x00000060
Reprogram Multicast Mask 0x20 to send to only
ports 10, 11, and 12. Multicast Mask Port CSR 0x80 0x00200040
0x00200A10
0x00200B10
0x00200C10
Associate DestID 0x03 with Multicast Mask
0x20 on all ports except port 11. The association
is performed in two steps:
1. Associate all ports with the mask.
2. Disassociate port 11. Multicast Association Selection CSR 0x84 0x00030020
Multicast Association Operations CSR 0x88 0x00000060

1. When a multicast mask is disassociated from a destID, the destID routing table value is 0xDF (drop packets).
Allow DestID 0xFF00 through FFFF to be
multicast according to the Device Routing Table
on all ports. Route Port Select Register 0x10070 0x00000000
