False Command IRQs Number of times a command failed because the
previous command was still being processed.
Command Status Errors Number of times the MAC-layer management
message was rejected.
Atmel Fatal Error Not used.
Unused Statistic Not used.
rxPktsDirected At the CCU, the number of times a reply from the EUM
is received with the correct HCRC (header cyclic
redundancy check). In the EUM, the number of times a
poll for the EUM is received from the CCU with the
correct HCRC.
rxPktsBroadcast At the CCU, the number of times an EUM succeeds in
a random access. Note that all EUM packets are
directed to the CCU, not broadcast. At the EUM, the
number of broadcast packets (see note 1) received
with the correct HCRC. These are also random access
opportunities.
rxPktsNoMatch Number of packets correctly received, but not directed
to, this station.
rxPktsDuplicate Number of duplicate payloads (see note 1) received
and discarded. Indicates that a MAC layer
acknowledgement was lost.
rxPktsRuntFail Number of packets received that were shorter than the
minimum size.
rxPktsLongFail Number of packets received that were longer than the
maximum size.
rxPktsHCRCFail Number of packets received with a MAC header CRC
failure (header corrupted).
rxPktsICVFail Number of packets received with an encryption (WEP,
wireless equivalent privacy) key mismatch (see note
3).
rxPktsFCSFail Number of packets received with a Frame Check
Sequence failure (payload corrupted).
rxPktsAssocFail Number of times a received packet had to be
discarded because too many EUMs were already
associated. [CCU only]
rxPktsIncomplete Number of times the receive DMA for a payload does
not complete (internal error).
rxPayloadsFailFull Number of times a received payload has to be
discarded because either no receive descriptor was
available, or there was not enough buffer space.
