Miscellaneous Counters
In addition to the statistics groups defined in previous sections, the ZL50404 has other statistics counters for its own
purposes. We have two counters for flow control – one counting the number of flow control frames received, and
another counting the number of flow control frames sent. We also have two counters, one for unicast frames sent,
and one for non-unicast frames sent. A broadcast or multicast frame qualifies as non-unicast. Furthermore, we
have a counter called “frame send fail.” This keeps track of FIFO under-runs, late collisions, and collisions that have
occurred 16 times.
