Reserved. Unknown During Read.
Receive Miss Count. The Receive Miss Count records the
number of frames that pass the destination address filter,
but fail to be received due to lack of bus availability or lack
of receive storage. Frames that are partially stored and
marked as overruns are included in the count. When the
most significant bit of the count is set, an optional interrupt
may be generated. The register is cleared automatically
following a read, writing to the register will have no effect.
Reserved. Unknown During Read.
Receive Runt Count. The receive runt count records the
total number of runt frames received, including those with
bad CRC. When the most significant bit of the count is set,
an optional interrupt may be generated. The register is
cleared automatically following a read, writing to the
register will have no effect.
