14.9.45 Packets Transmitted (128-255 Bytes) Count -
PTC255 (040E0h; RC)
This register counts the number of packets transmitted that are 128-255 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.
14.9.46 Packets Transmitted (256-511 Bytes) Count -
PTC511 (040E4h; RC)
This register counts the number of packets transmitted that are 256-511 bytes (from <Destination
Address> through <CRC>, inclusively) 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. This register counts all packets, including standard and secure packets. Management packets
must never be more than 200 bytes.
14.9.47 Packets Transmitted (512-1023 Bytes) Count -
PTC1023 (040E8h; RC)
This register counts the number of packets transmitted that are 512-1023 bytes (from <Destination
Address> through <CRC>, inclusively) 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. This register counts all packets, including standard and secure packets. Management packets
must never be more than 200 bytes.
14.9.48 Packets Transmitted (1024 Bytes or Greater)
Count - PTC1522 (040ECh; RC)
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 (for example, collisions in
half-duplex mode) are not included in this register. This register only increments if transmits are
enabled.
