Hello @Ephraimoved (Community Member)

There are two ADC ADC1 and ADC4

You can check corresponding RCC peripheral clock enable register.

RCC AHB2ENR1 Bit 10 ADC1EN:

ADC1 clock enable Set and cleared by software.

0: ADC1 clock disabled

1: ADC1 clock enabled

RCC AHB3ENR Bit 5 ADC4EN:

ADC4 clock enable Set and cleared by software.

0: ADC4 clock disabled

1: ADC4 clock enabled

In order to use ADCx on U5 device, you also need to set

PWR SVMCR Bit 30 ASV: VDDA independent analog supply valid.

Best regards

Romain
