This register counts the number of good packets received that are 256-511 bytes (from
<Destination Address> through <CRC>, inclusively) in length. Packets that are
counted in the Missed Packet Count register are not counted in this register. This
register does not include received flow control packets and increments only if receives
are enabled.
Packets Received [512–1023 Bytes] Count - PRC1023 (0x0406C; RW)
This register counts the number of good packets received that are 512-1023 bytes
(from <Destination Address> through <CRC>, inclusively) in length. Packets that are
counted in the Missed Packet Count register are not counted in this register. This
register does not include received flow control packets and increments only if receives
are enabled.
Packets Received [1024 to Max Bytes] Count - PRC1522 (0x04070;
RW)
This register counts the number of good packets received that are from 1024 bytes to
the maximum (from <Destination Address> through <CRC>, inclusively) in length. The
maximum is dependent on the current receiver configuration (such as, LPE, etc.) and
the type of packet being received. If a packet is counted in the Receive Oversized Count
register, it is not counted in this register (see
include received flow control packets and only increments if the packet has passed
address filtering and receives are enabled.
Due to changes in the standard for maximum frame size for VLAN tagged frames in
802.3, this device accepts packets which have a maximum length of 1522 bytes. The
RMON statistics associated with this range has been extended to count 1522 byte long
packets.
Good Packets Received Count - GPRC (0x04074; R)
This register counts the number of good (non-erred) packets received of any legal
length. The legal length for the received packet is defined by the value of LPE (see
Section
only counts packets that pass filtering. This register only increments if receives are
enabled. This register does not count packets counted by the Missed Packet Count
(MPC) register.
