Forum Post: RE: TM4C129XNCZAD: ADC raw interrupt does not triggered if using PIOSC for both system clock and ADC clock

Hi, cb1_mobile, Base on my question, I am suspecting that the ADC digital block has to get the clock from the PLL in order for it to work properly. if PIOSC clock is used without the PLL, ADC seems to be not working as no interrupt is triggered. Could someone from TI confirm my doubt?
