- * The setting of these parameters is conditioned to ADC state:

- * @note Caution: For Injected Context Queue use, a context must be fully

- * HAL_ADCEx_InjectedConfigChannel() must be equal to the value of parameter
- * InjectedNbrOfConversion for each context.

- * (InjectedNbrOfConversion = 3), HAL_ADCEx_InjectedConfigChannel() must be

- * This function must not be called to configure a 4th injected channel:

- * 3 injected ranks (InjectedNbrOfConversion = 3),
- * HAL_ADCEx_InjectedConfigChannel() must be called once for each channel and
