ADC_InjectionConfTypeDef::ExternalTrigInjecConv field

Selects the external event used to trigger the conversion start of injected group. If set to ADC_INJECTED_SOFTWARE_START, external triggers are disabled. If set to external trigger source, triggering is on event rising edge. This parameter can be a value of ADCEx_External_trigger_Source_Injected Note: This parameter must be modified when ADC is disabled (before ADC start conversion or after ADC stop conversion). If ADC is enabled, this parameter setting is bypassed without error reporting (as it can be the expected behaviour in case of another parameter update on the fly) 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.
