MacControl-
FramesXmtd
MAC Control Frames Transmitted is the count of
MAC control frames transmitted by the IP1000A
LF. Note, acControl-FramesXmtd does not include
MAC control frames transferred to the IP1000A LF
by the host system via the transmit DMA process.
An UpdateStats interrupt (UpdateStats bit within
the
IntStatus
register)
will
occur
when
MacControlFramesXmtd
reaches
a
value
of
0xC000. MacControlFramesXmtd is enabled by
writing a logic 1 to the StatisticsEnable bit in the
MACCtrl
register,
and
a
logic
0
to
the
MacControlFramesXmtd
bit
within
the
StatisticsMask register.

McstFramesRcvd
Ok
Broadcast Frames Received OK is the count of the
number of frames that are successfully received to a
group destination address other than the broadcast
address (0xFFFFFFFFFFFF). McstFramesRcvdOk
does not include frames received with frames too
long, FCS, length or alignment errors, or frames lost
due to internal MAC sublayer error (i.e. overrun).
McstFramesRcvdOk will wrap around to zero after
reaching 0xFFFFFFFF. See IEEE 802.3 Clause
30.3.1.1.21.
An UpdateStats interrupt (UpdateStats bit within
the
IntStatus
register)
will
occur
when
McstFramesRcvdOk
reaches
a
value
of
0xC0000000. McstFramesRcvdOk is enabled by
writing a logic 1 to the StatisticsEnable bit in the
R/W
