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
