DP83620: direction detection (MDIX) issues? wrong direction detected?

AnBer

Part Number: DP83620

Team,

I have seen the below post that talks about an issue with MDIX mode that detects wrongly the direction:
https://e2e.ti.com/support/interface/f/138/t/462123

-Do we have more information on what culd lead to a wrong direction been recognized?
what tests could be down to narrow downth issue?

An other question:
-what can happen if JTAG is used but reserved pins are left unconnected?
-Would it place the device in some test mode that could alter the operation?

thanks in advance,
