Register Descriptions
All packets received have their octets summed into this register, regardless of their length, whether
they are erred, or whether they are flow control packets. This register includes bytes received in a
packet from the <Destination Address> field through the <CRC> field, inclusively. This register
only increments if receives are enabled.
Table 13-130. TORL and TORH Register Bit Descriptions
13.7.42 Total Octets Transmitted
TOTL (040C8h; R/W / TOTH (040CCh; R)
These registers make up a 64-bit register that counts the total number of octets transmitted. This
register resets each time the upper 32 bits are read (TOTH). In addition, it sticks at
FFFF_FFFF_FFFF_FFFFh 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, inclusively.
Octets transmitted as part of partial packet transmissions (collisions in half-duplex mode) are not
included in this register. This register only increments if transmits are enabled.
