Intel LXT971A, LXT972A, and LXT972M Transceivers Specification Update
Document Number: 249354
Revision Number: 010
Revision Date: January 13, 2005
Errata
1.
Incorrect Auto-Negotiation Link Partner Base Page Ability Register
Problem:
Upon completing the parallel detection function, the Auto-Negotiation Link Partner Base Page
Ability Register (Register 5) should be updated to reflect the link partner’s capability. Register 5 is
not updated correctly and always reads 0000h.
Workaround:
The Status Register #2 (Register 17) is properly updated with the arbitrated link status information
and can be used to identify link speed and duplex status.
Status:
This erratum has been previously fixed.
2.
Incorrect Auto-Negotiation Next Page
Problem:
The Auto-Negotiation Next Page state machine functions incorrectly and does not support Next
Page operations.
Workaround:
Bit 4.15 in the Auto-Negotiation Advertisement Register must be set to 0 (port has no ability to
send multiple pages).
Status:
This erratum has been previously fixed.
3.
Incorrect Remote Fault
Problem:
In fiber mode, the Remote Fault bit (Register bit 1.4) in MII Status Register #1 is used to report
receipt of the Far End Fault Indication (FEFI) code to the MAC. The Remote Fault bit fails to
indicate receipt of the FEFI code under certain conditions.
This occurs only when the following conditions are true:
The device is operating in fiber mode, AND
The device hardware configuration is set to enable auto-negotiation.
Workaround:
Strap the LED/CFG1 pin to ground to disable auto-negotiation.
Status:
This erratum has been previously fixed.
