8.4.4 PHY Autoscan Registers
Note: These register hold the current values of the PHY registers only when Autoscan (see Section 5.5.8,
“Autoscan Operation” on page 102) is enabled and the IXF1104 is configured in copper mode.
These registers are not applicable in fiber mode.
TxTagged
Number of OK frames with VLAN tag.
(Type field = 0x8100).
Port_Index +
0x55
R 0x00000000
TxCRCError
Number of frames transmitted with a
legal size but with the wrong CRC field
(also called FCS field).
Port_Index +
0x56
R 0x00000000
TxPauseFrames
Number of pause MAC frames
transmitted.
Port_Index +
0x57
R 0x00000000
TxFlowControlCollisions
Send
Intentionally generates collisions to
curb reception of incoming traffic due to
insufficient memory available for
additional frames. The port must be in
half-duplex mode with flow control
enabled.
NOTE: To receive a correct statistic, a
last frame may have to be
transmitted after the last flow
control collisions send.
NOTE: NA - half-duplex only
