Receive Fragment Count - RFC (0x040A8; R)
This register counts the number of received frames that passed address filtering, and
were less than minimum size (64 bytes from <Destination Address> through <CRC>,
inclusively), but had a bad CRC (this is slightly different from the Receive Undersize
Count register). This register only increments if receives are enabled.
Receive Oversize Count - ROC (0x040AC; R)
This register counts the number of received frames that passed address filtering, and
were greater than maximum size. Packets over 1522 bytes are oversized if LPE is 0b. If
LPE is 1b, then an incoming, packet is considered oversized if it exceeds 16384 bytes.
If receives are not enabled, this register does not increment. These lengths are based
on bytes in the received packet from <Destination Address> through <CRC>,
inclusively.
Receive Jabber Count - RJC (0x040B0; R)
This register counts the number of received frames that passed address filtering, and
were greater than maximum size and had a bad CRC (this is slightly different from the
Receive Oversize Count register).
Packets over 1522 bytes are oversized if LPE is 0b. If LPE is 1b, then an incoming
packet is considered oversized if it exceeds 16383 bytes.
If receives are not enabled, this register does not increment. These lengths are based
on bytes in the received packet from <Destination Address> through <CRC>,
inclusively.
