For ADC architectures with the ADCn->SCANINPUTSEL register, use ADC_ScanSingleEndedInputAdd() to configure single-ended scan inputs or ADC_ScanDifferentialInputAdd() to configure differential scan inputs. ADC_ScanInputClear() is also provided for applications that need to update the input configuration.
