Notes
On this STM32 serie, setting of external trigger edge is
performed using function
LL_ADC_REG_StartConversionExtTrig().
Availability of parameters of trigger sources from timer
depends on timers availability on the selected device.

Function name
__STATIC_INLINE uint32_t LL_ADC_REG_GetTriggerSource
(ADC_TypeDef * ADCx)
Function description
Get ADC group regular conversion trigger source: internal (SW
start) or from external IP (timer event, external interrupt line).
Parameters
ADCx: ADC instance
Return values
Returned: value can be one of the following values:
LL_ADC_REG_TRIG_SOFTWARE
LL_ADC_REG_TRIG_EXT_TIM1_CH1
LL_ADC_REG_TRIG_EXT_TIM1_CH2
LL_ADC_REG_TRIG_EXT_TIM1_CH3

LL_ADC_REG_TRIG_EXT_TIM4_CH4
LL_ADC_REG_TRIG_EXT_TIM5_CH1
LL_ADC_REG_TRIG_EXT_TIM5_CH2

LL_ADC_REG_TRIG_EXT_TIM8_CH1
LL_ADC_REG_TRIG_EXT_TIM8_TRGO
LL_ADC_REG_TRIG_EXT_EXTI_LINE11
Notes
To determine whether group regular trigger source is internal
(SW start) or external, without detail of which peripheral is
selected as external trigger, (equivalent to
"if(LL_ADC_REG_GetTriggerSource(ADC1) ==
LL_ADC_REG_TRIG_SOFTWARE)") use function
LL_ADC_REG_IsTriggerSourceSWStart.
Availability of parameters of trigger sources from timer
depends on timers availability on the selected device.
