0x000620
CRC Error
This counter is incremented once for every received packet
which meets all the following conditions (i.e. logical AND of the
following conditions):
1. Packet data length is between 64 and MAXFRAMESIZE
bytes inclusive (i.e. valid packet data length per IEEE std).
2. Packet has invalid CRC (non-A also counted packets with
odd number of nibbles).
3. Collision Event has not been detected.
4. Late Collision Event has not been detected.
5. Rx Error Event has not been detected.

0x000624
Oversize Frames
This counter is incremented once for every received packet
which meets all the following conditions (i.e. logical AND of the
following conditions):
1. Packet data length is greater than and MAXFRAMESIZE.
2. Packet has valid CRC.
3. Rx Error Event has not been detected.

0x000628
Fragments
This counter is incremented once for every received packet
which meets all the following conditions (i.e. logical AND of the
following conditions):
1. Packet data length is less than 64 bytes -OR- packet without
SFD and is less than 64 bytes in length.
2. Collision Event has not been detected.
3. Late Collision Event has not been detected.
4. Rx Error Event has not been detected.

0x000630
Collision
This counter is incremented once for every received packet
which meets both of the following conditions (i.e. logical AND of
the following conditions):
1. Collision Event has been detected.
2. Rx Error Event has not been detected.
-
0x000634
Late Collision
This counter is incremented once for every received packet
which meets both of the following conditions (i.e. logical AND of
the following conditions):
1. Late Collision Event has been detected.
2. Rx Error Event has not been detected.
-
0x000638
Frames 64 Bytes
This counter is incremented once for every received and trans-
mitted packet with size of 64 bytes. This counter includes local,
dropped and transmitted packets.
