13.7.49 Packets Transmitted (512-1023 Bytes) Count
PTC1023 (040E8h; R)
This register counts the number of packets transmitted that are 512-1023 bytes (from <Destination
Address> through <CRC>, inclusively) in length. Partial packet transmissions (collisions in half-
duplex mode) are not included in this register. This register only increments if transmits are
enabled.This register counts all packets, including standard packets, secure packets, packets
received over the SMBus, and packets generated by the ASF function.

13.7.50 Packets Transmitted (1024 Bytes or Greater) Count
PTC1522 (040ECh; R)
This register counts the number of packets transmitted that are 1024 or more bytes (from
<Destination Address> through <CRC>, inclusively) in length. Partial packet transmissions
(collisions in half-duplex mode) are not included in this register. This register only increments if
transmits are enabled.
Due to the maximum frame size for VLAN tagged frames in IEEE Standard 802.3ac, these
Ethernet controllers transmit 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, including standard packets, secure packets, packets received over the
SMBus

, and packets generated by the ASF function.
