13.7.30Good Packets Transmitted Count

GPTC (04080h; R)

This register counts the number of good (no errors) packets transmitted. A good transmit packet is considered one that is 64 or more bytes in length (from <Destination Address> through <CRC>, inclusively) in length. This does not include transmitted flow control packets. This register only increments if transmits are enabled.

13.7.31Good Octets Received Count

GORCL (04088h; R)/GORCH (0408Ch; R)

These registers make up a 64-bit register that counts the number of good (no errors) octets received. This register includes bytes received in a packet from the <Destination Address> field through the <CRC> field, inclusively. This register resets each time the upper 32 bits are read (GORCH).

In addition, it sticks at FFFFh_FFFFh_FFFFh_FFFFh when the maximum value is reached. Only octets of packets that pass address filtering are counted in this register. This register only increments if receives are enabled.

These octets do not include octets of received flow control packets.
