Register Descriptions
This register does not increment when flow control packets are received.
Table 13-125. RNBC Register Bit Description
13.7.34 Receive Undersize Count
RUC (040A4h; 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), and had a
valid CRC. This register only increments if receives are enabled.
Table 13-126. RUC Register Bit Description
13.7.35 Receive Fragment Count
RFC (040A8h; 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.
