McstOctetRcvdOk Multicast Octets Received OK is the count of the
number of data and padding octets in frames, to a
group
destination
address
other
than
the
broadcast address (0xFFFFFFFFFFFF), that are
successfully received. McstOctetRcvdOk 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).
McstOctetRcvdOk will wrap around to zero after
reaching 0xFFFFFFFF.
All IP1000A LF byte and octet count based
statistic registers include the VLAN tag (4 octets)
regardless of whether or not the IP1000A LF is
adding (on frame transmission) or removing (on
frame reception) the VLAN tag automatically.
An UpdateStats interrupt (UpdateStats bit within
the
IntStatus
register)
will
occur
when
McstOctetRcvdOk
reaches
a
value
of
0xC0000000. McstOctetRcvdOk is enabled by
writing a logic 1 to the StatisticsEnable bit in the
MACCtrl
register,
and
a
logic
0
to
the
McstOctetRcvdOk bit within the StatisticsMask
register.
