gpio behavior for tlv320aic3204 (open drain or not?)

frederic douit

Hello,

I want to use pin MFP5 to activate a secondary chip. It needs to be pulled high for off state and pulled low for on state.

I set gpio as outpout purpose and set high (00001101 or 0D), chip is disable = ok.

I set gpio as outpout purpose and set low (00001100 or 0C), chip is still disable.

I'm wondering if gpio are open drain or not?

Is someone can help me on this please?

thank you

I think I figured it out. I set register in "lowpower to active" section and it seems to be good now
