Description
Use this command to verify that the Content Addressable Memory (CAM) is
functionally OK by performing hit and miss tests. The CAM is used by
QuickLoop to translate the SID.
When a CAM is presented with data, it checks if the data is present in its memory.
A hit means the data is found in the CAM. A miss means the data is not found.
In this test, the CAM is filled with 4 kinds of data patterns:
1. A walking 1
2. A walking 0
3. A random pattern
4. An inverted version of the random pattern above
Once filled with each of the patterns above, a frame is sent and looped back
internally. If a hit is expected (when the random or inverted random pattern is
used) the original SID in the frame transmitted is received translated with the
