Receive Packet 256-511 Statistics Counter (RX_PKT_256_511)
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 512-1023 Statistics Counter (RX_PKT_512_1023)
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 1024-1518 Statistics Counter (RX_PKT_1024_1518)
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 Undersize Statistics Counter (RX_PKT_UNDERSIZE)
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 packets received that were between 256-
RO — 511 octets in length (including bad packets). rx_statvec[13:8] is
used to implement this counter.
Type Default
Counts the number of packets received that were between 512-
RO — 1023 octets in length (including bad packets). rx_statvec[13:9] is
used to implement this counter.
Type Default
Counts the number of packets received that were between 1024-
RO — 1518 octets in length (including bad packets). rx_statvec[13:0] is
used to implement this counter.
Type Default
Counts the number of packets received that were less than 64
RO — octets long and were otherwise well formed. rx_statvec[13:6] is
used to implement this counter.
