8.18.55 Packets Transmitted [256-511 Bytes] Count - PTC511 (0x40E4;
RC)
This register counts the number of packets transmitted that are 256-511 bytes (from <Destination
Address> through <CRC>, inclusive) in length. Partial packet transmissions (for example, collisions in
half-duplex mode) are not included in this register. This register only increments if transmits are
enabled (TCTL.EN is set). This register counts all packets. Management packets must never be more
than 200 bytes.
8.18.56 Packets Transmitted [512-1023 Bytes] Count - PTC1023
(0x40E8; RC)
This register counts the number of packets transmitted that are 512-1023 bytes (from <Destination
Address> through <CRC>, inclusive) in length. Partial packet transmissions (for example, collisions in
half-duplex mode) are not included in this register. This register only increments if transmits are
enabled (TCTL.EN is set). This register counts all packets. Management packets must never be more
than 200 bytes.
8.18.57 Packets Transmitted [1024 Bytes or Greater] Count - PTC1522
(0x40EC; RC)
This register counts the number of packets transmitted that are 1024 or more bytes (from <Destination
Address> through <CRC>, inclusive) in length. Partial packet transmissions (for example, collisions in
half-duplex mode) are not included in this register. This register only increments if transmits are
enabled (TCTL.EN is set).
Due to changes in the standard for maximum frame size for VLAN tagged frames in 802.3, the I210
transmits packets that have a maximum length of 1522 bytes. The RMON statistics associated with this
range has been extended to count 1522 byte long packets. This register counts all packets.
Management packets must never be more than 200 bytes. If CTRL.EXT_VLAN is set, packets up to
1526 bytes are counted by this counter.
8.18.58 Multicast Packets Transmitted Count - MPTC (0x40F0; RC)
This register counts the number of multicast packets transmitted. This register does not include flow
control packets and increments only if transmits are enabled (TCTL.EN is set).
