DP83826AI: Mismatched setting of Auto-MDIX between strap and register value

Part Number: DP83826AI

Hello,

The DP83826A is designed to provide EtherCAT connectivity. For that, it was designed to operate in enhanced mode (ModeSelect = floating), and the strap9 is set to 0 and it was confirmed using register SOR1. This should enable Auto-MDIX. 

However, when I checked register CR1 its value was 0.

What could possibly be the root cause? and how to fix it? How does Auto-MDIX disable affect EtherCAT connectivity?

With best regards
