Multicast Hash Registers
Multicast Hash registers are used to distribute multicast traffic. 16 registers are used to form a 4-entry array; each
entry has 27 bits, with each bit representing one port. Any port not belonging to a trunk group should be
programmed with 1. Ports belonging to the same trunk group should only have a single port set to “1” per entry.
The port set to “1” is picked to transmit the multicast frame when the hash value is met.
Bit [:0]
Reserved
Bit [6:4]
000 Normal
001 Trunk Mode. Enable Trunk group for Gigabit port 1 and 2 in
managed mode. In unmanaged mode Trunk 2 is enable/disable
using input pin TRUNK2.
010 Single Ring with G1
100 Single Ring with G2
111 Dual Ring Mode
