Hi Igorpadykov,

could you elaborate your answer, please?

Why isn't it designed for that porpose? What is the difference between the SoC ADC module and an external serial ADC?

Thanks

please refer to Chapter 14 Analog-to-Digital Converter (ADC)

Ok,

due to the ADC module that cannot be used as GPIO.

Thanks
