DP83TC812S-Q1: Failed to communicate with peer while using DP83TC812S-Q1

Part Number: DP83TC812S-Q1

Hi, TI

  We're experiencing a link down issue. 

  Register 0x871 shows that the current SQI value is 0, register 0x1 shows that the current state is Link up, and it is currently not able to communicate with the peer.

  After half an hour, everything returned to normal, such as registers, communication, etc.

  Why does this happen? When it happens again, what should we focus on to resolve the issue once and for all?

Best Regards,

Chen
