STM32F7 "clause 45" MDIO?

How do I configure the ETH IP to send a "Clause 45" compliant message to the PHY? We are using one that uses an OP code of '00' to access an extended register set. 


The processor is STM32F745IET6. I am programming with Cube 4.18.0 and using HAL library version 1.5.1.

I have looked this up in RM0385 Rev 6 and can find nothing on it.


Information that clued me in to "clause 45" is found at MDIO Background – Total Phase
