MAC TX Statistics Register Overview
The MAC TX Statistics Registers contain all the MAC transmit statistic counters and are
cleared when read. The software must poll these registers to accumulate values and 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
IXF1110 10-Port 1000 Mbps Ethernet Media Access Controller
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
Name
covers the MAC TX Statistics Registers for all 10 MAC ports. The address is
The total number of packets received that are
less than 96 bit times, which corresponds to a 4-
byte frame with a well formed preamble and
SFD. This counter indicates fragment sizes
illegal in all modes, and is only fully updated after
reception of a good frame following a fragment.
Note: RxShortErrors is not supported in the
IXF1110 MAC. Any runt or short packets
received are not counted in this register.
Gigabit half-duplex event only
Note: N/A - half-duplex only
Records the number of sequencing errors that
occur.
Records the number of symbol errors
encountered. The counter increments once for
each packet that encounters symbol errors
during reception. Symbol errors between
packets are not counted.
