ADC_InjectionConfTypeDef::InjectedNbrOfConversion field
Specifies the number of ranks that will be converted within the injected group sequencer. To use the injected group sequencer and convert several ranks, parameter 'ScanConvMode' must be enabled. This parameter must be a number between Min_Data = 1 and Max_Data = 4. Caution: this setting impacts the entire injected group. Therefore, call of HAL_ADCEx_InjectedConfigChannel() to configure a channel on injected group can impact the configuration of other channels previously set.
