Register Descriptions

13.7.49Packets 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.

PTC1023	31:0	0b	Number of packets transmitted that are 512-1023 bytes in length.

13.7.50Packets 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 SMBus1, and packets generated by the ASF function.
