Function Description
associated location (The result will be returned). Because more than one entry may match
the searching condition (by port, by address, etc) at the same time, the CPU should
continue to restart the search engine until the Command Result = Entry Not is found to
confirm that no other matching entries exist.

Step
The user needs ADM6926 to
forward the specified unicast packet
(DA = 48’h0012_3456_789a and
Forwarding Group = 2) to port 3
forever.
Step 1: Check the Busy bit. If Busy = 1’b0, go to the step 2. If Busy = 1’b1, wait.
Step 2: Write 32’h3456_789a into control register 0.
Step 3: Write 32’h5c62_0012 into the control register 1.
Step 4: Write 32’h0 into the control register 2 to start the “Create” operation.
Step 5: Read the status register 2 to check the busy bit. If Busy = 1’b0, check the
Command Result to see if the create operation is successful. If Busy = 1’b1, wait for
completion.
Step 1: Check the Busy bit. If Busy = 1’b0, go to the step 2. If Busy = 1’b1, wait.
Step 2: Write 32’h4567_89ab into control register 0.
Step 3: Write 32’h1ca3_0123 into the control register 1.
Step 4: Write 32’h0 into the control register 2 to start the “Create” operation.
Step 5: Read the status register 2 to check the busy bit. If Busy = 1’b0, check the
Command Result to see if the create operation is successful. If Busy = 1’b1, wait for
completion.
The user needs the ADM6926 to
forward the specified multicast
packet (DA = 48’h0123_4567_89ab
and Forwarding Group = 3) to port 5
only. This address could be aged.
