4.4.3.9.37 Total Octets Received – TOR (0x040C4; R);
Field
TOR
Bit(s)
Initial
Value
Description
31:0
0x0
Number of total octets received – upper 4 bytes.
This register counts the total number of octets received. In addition, it sticks at 0xFFFF_FFFF when the
maximum value is reached.
All packets received passing at least one of the L2 receive filters have their octets summed into this
register, regardless of their length, whether they are erred, or whether they are flow control packets. It
includes bytes received in a packet from the Destination Address field through the CRC field, inclusively.
This register only increments if receives are enabled.
Broadcast rejected packets are counted in this counter (in contradiction to all other rejected packets
that are not counted).
4.4.3.9.38 Total Packets Received – TPR (0x040D0; R)
Field
TPR
Bit(s)
Initial
Value
Description
31:0
0x0
Number of all packets received.
This register counts the total number of all packets received. All packets received are counted
regardless of their length, whether they are erred, or whether they are flow control packets. The
register only increments if receives are enabled.
Broadcast rejected packets are counted in this counter (in contradiction to all other rejected packets
that are not counted). TPR might count packets interrupted by link disconnect although they have a
CRC error.
4.4.3.9.39 Total Packets Transmitted – TPT (0x040D4; R)
Field
TPT
Bit(s)
Initial
Value
Description
31:0
0x0
Number of all packets transmitted.
This register counts the total number of all packets transmitted. All packets transmitted are counted in
this register, regardless of their length, or whether they are flow control packets.
Partial packet transmissions (collisions in half-duplex mode) are not tallied. This register only
increments if transmits are enabled. It counts all packets, including standard packets, secure packets,
packets received over the SMBus.
