I would know more about PA4(Audio DAC OUT) PC3(PDM OUT) and PC4

It seems that PA4 comes from the Âµcontroller's DAC (additionnal functions ADC12_IN4

/DAC_OUT1) ?

PC3 comes from microphone MP45DT02 it s clear!

PC4 is an analogic enter what I could use freely?

Each enter go with low/high filter (if someone could explain me more precisely thanks)

And if I want use these analogic enter I must play with my Âµcontroler to order the CS43L22 ?

Thanks
