QorIQ EMI_MDIO controller ACK bit checking

Hi,

 

 

Does Ethernet Management Interface controller in QorIQ processors (namely LS1021A and T1040) check the low level on the MDIO line during the second turnaround bit (ACK) for read transactions? What if an external PHY won't set this bit low? Will the read transaction be aborted by controller or it will be completed as normal?

MDIO read transaction
