Hello,

I would like to use ADCINAx or ADCINBx pins like GPIO pins.

How can I use?

How can I init these pins like a GPIO pin?

For Ex;

I want to define ADCINA7 pin as GPIO, input/output etc...

Hi Mert, unfortunately ADCINA3, A5, and A7 cannot be configured as GPIO. To determine which analog inputs can be configured, please review the "Signal Descriptions" table in the device datasheet: https://ti.com/lit/SPRS698.

For other analog inputs which can be configured, please look into the AIOMUX1 register which is documented in the technical reference manual: https://ti.com/lit/SPRUH18

Regards, Joe
