Use of dedicated analog input and dual-purpose analog pins for digital signals on Max10

I have a MAX 10 design (part: 10M08SAM15317G) in which I'm attempting to use the MAX 10 ADC Hard IP Block to capture signals on the dedicated Analog Input (Pin ANAIN[1]) while preserving the the dual...

    No, you cannot use the rest of the dual-purpose pins as GPIO pins if you are using the ADC, despite you are just using the ANAIN pins.

OK, that is definitive.

Can you point me to the documentation where this is specified? If not, I would suggest that the documentation is updated to make this clear if the ADC Hard block is used, all digital IO, including the MUXed, non-dedicated inputs are not available for digital IO.

Thank you for your help!
