Table 77. MAC RX Statistics ($ Port_Index + 0x20 - Port_Index + 0x39) (Sheet 1 of 4)
MAC RX Statistics Register Overview
The MAC RX Statistics Registers contain the MAC receiver statistic counters and are cleared when
read. The software polls these registers and accumulates values to ensure that the counters do not
wrap. The 32-bit counters wrap after approximately 30 seconds.

1. R = Read Only; CoR = Clear on Read; W = Write; R/W = Read/Write
2. When sending in large frames, the counters can only deal with certain limits. The behavior of the
LongErrors and VeryLongErrors counters is as follows: VeryLongErrors counts frames that are
2*MaxFrameSize, dependent on where the MaxFrameSize variable is set. If MaxFrameSize sets greater
than half of the available count in RxOctetsBad (2^14-1), VeryLongErrors is never incremented, but
LongErrors is incremented. This is due to a limitation in the counter size, which means that an accurate
count will not occur in the RxOctetsBAD counter if the frame is larger than 2^14-1. MaxFrameSize is
determined by the settings in the

Counts the bytes received in all legal frames,
including all bytes from the destination MAC
address to and including the CRC. The initial
preamble and SFD bytes are not counted.
Counts the bytes received in all bad frames of a
size greater than or equal to 64 bytes. A bad
frame is defined as a properly framed packet
containing a CRC, alignment error, or code
violation. The 64-byte value is measured from
the destination address, up to and including
CRC. The initial preamble and SFD are not
included in this value.
Note: This register does not increment the Bad
Octet count on undersized receive packets.
The total number of unicast packets received
(excluding bad packets)
Note: This count includes non-pause control and
VLAN packets, which are also counted in other
counters. These packet types are counted twice.
Take care when summing register counts for
reporting MIB information.
The total number of multicast packets received
(excluding bad packets)
Note: This count includes pause control packets,
which are also counted in the PauseMacControl-
ReceivedCounter. These packet types are
counted twice. Take care when summing register
counts for reporting MIB information.
The total number of Broadcast packets received
(excluding bad packets)
The total number of packets received (including
bad packets) that were 64 octets in length.
Incremented for tagged packets with a length of
64 bytes, including tag field
