8.18.47 Total Octets Received - TORH (0x40C4; RC)

8.18.48 Total Octets Transmitted - TOTL (0x40C8; RC)

These registers make up a 64-bit register that counts the total number of octets transmitted. This

This register sticks at 0xFFFF_FFFF_FFFF_FFFF when the maximum value is reached.

All transmitted packets have their octets summed into this register, regardless of their length or

whether they are flow control packets. This register includes bytes transmitted in a packet from the

<Destination Address> field through the <CRC> field, inclusive.

Octets transmitted as part of partial packet transmissions (for example, collisions in half-duplex mode)

are not included in this register. This register only increments if transmits are enabled (TCTL.EN is set).

8.18.49 Total Octets Transmitted - TOTH (0x40CC; RC)

8.18.50 Total Packets Received - TPR (0x40D0; RC)

This register counts the total number of all packets received. All packets received are counted in this

This register only increments if receives are enabled (RCTL.RXEN is set).

Notes:

1. Broadcast rejected packets are counted in this counter (as opposed to all other rejected packets

that are not counted).

2. Runt packets smaller than 25 bytes cannot be counted by this counter.

3. TPR can count packets interrupted by a link disconnect although they have a CRC error.
