Data Sheet

Zarlink Semiconductor Inc.
10.4.1.8 Fragments
Counts number of frames received with size less than 64 bytes and with bad FCS.
10.4.1.9 Jabbers
Counts number of frames received with size exceeding maximum frame size and with bad FCS.
10.4.1.10 Collisions
Counts number of collision events detected.
Only a best estimate since collisions can only be detected while in transmit mode, but not while in receive
mode.
10.4.1.11 Packet Count for Different Size Groups
Six different size groups – one counter for each:
Pkts64Octets
for any packet with size = 64 bytes
Pkts65to127Octets
for any packet with size from 65 bytes to 127 bytes
Pkts128to255Octets
for any packet with size from 128 bytes to 255 bytes
Pkts256to511Octets
for any packet with size from 256 bytes to 511 bytes
Pkts512to1023Octets
for any packet with size from 512 bytes to 1023 bytes
Pkts1024to1518Octets
for any packet with size from 1024 bytes to 1518 bytes
counts both good and bad packets.
Miscellaneous Counters
In addition to the statistics groups defined in previous sections, the MVTX2802AG 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.
