Register Descriptions

13.7.45Packets Transmitted (64 Bytes) Count

PTC64 (040D8h; R)

This register counts the number of packets transmitted that are exactly 64 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 does not include transmitted flow control packets (which are 64 bytes in length). 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.

PTC127 (040DCh; R)

This register counts the number of packets transmitted that are 65-127 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 SMBus1, and packets generated by the ASF function.
