Packets 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.
