I am working on an application where the ADAU1701 is receiving serial audio data on Multifunction Pin 1 that has been configured as serial audio data input.
It seems that this pin is always pulled up. The same stands for all other multifunction pins when set as SDATA inputs.
I was wondering if those can be pulled low.
On another application using an ADAU1761 I can choose to pull-up/down the SDATA lines. But it does not seem possible with an ADAU1701. Is that correct or I just need to write the right register in order to do that?
