Receive Packet Unicast Statistics Counter (RX_PKT_UNICAST)
A read of the low byte of this counter returns that byte and latches the upper bytes for later reading. A read of any
of the other bytes returns the previously latched value for that byte. The low address addresses the low byte.

Packets Received Statistics Counter (RX_PKT_RCVD)
A read of the low byte of this counter returns that byte and latches the upper bytes for later reading. A read of any
of the other bytes returns the previously latched value for that byte. The low address addresses the low byte.

Receive Packet 64 With Good CRC Statistics Counter (RX_PKT_64_GOOD_CRC)
A read of the low byte of this counter returns that byte and latches the upper bytes for later reading. A read of any
of the other bytes returns the previously latched value for that byte. The low address addresses the low byte.

Receive Packet 1518 With Good CRC Statistics Counter (RX_PKT_1518_GOOD_CRC)
A read of the low byte of this counter returns that byte and latches the upper bytes for later reading. A read of any
of the other bytes returns the previously latched value for that byte. The low address addresses the low byte.

IPUG39_02.9, December 2010
Type Default
Counts the number of good packets received that were directed to
RO — a single address. rx_statvec[15] and rx_statvec[16] are used to
implement this counter.
Type Default
Counts the number of packets received (including bad packet,
RO — broadcast and multicast packets). rx_statvec[15] and
rx_statvec[16] are used to implement this counter.
Type Default
Counts the number of packets received with length less than 64
RO — and with a good crc. rx_statvec[13:6] and rx_statvec[17] are used
to implement this counter.
Type Default
Counts the number of packets received with length more than
RO — 1518 and with a good crc. rx_statvec[21] and rx_statvec[17] are
used to implement this counter.
