stop: in this case, ADC group injected is
controlled only from ADC group regular.
ADC interruptions for configuration (interruption enable or disable)
LL_ADC_IT_EOCS
ADC interruption ADC group regular end of unitary conversion or
sequence conversions (to configure flag of end of conversion, use
function
LL_ADC_IT_OVR
ADC interruption ADC group regular overrun
LL_ADC_IT_JEOS
ADC interruption ADC group injected end of sequence
conversions (Note: on this STM32 serie, there is no flag ADC
group injected end of unitary conversion. Flag noted as "JEOC" is
corresponding to flag "JEOS" in other STM32 families)
LL_ADC_IT_AWD1
ADC interruption ADC analog watchdog 1
Multimode - DMA transfer
LL_ADC_MULTI_REG_DMA_EACH_ADC
ADC multimode group regular conversions
are transferred by DMA: each ADC uses its
own DMA channel, with its individual DMA
transfer settings
LL_ADC_MULTI_REG_DMA_LIMIT_1
ADC multimode group regular conversions
are transferred by DMA, one DMA channel for
all ADC instances (DMA of ADC master), in
limited mode (one shot mode): DMA transfer
requests are stopped when number of DMA
data transfers (number of ADC conversions)
is reached. This ADC mode is intended to be
used with DMA mode non-circular. Setting of
DMA mode 1: 2 or 3 (dual or triple mode) half-
words one by one, ADC1 then ADC2 then
ADC3.
LL_ADC_MULTI_REG_DMA_LIMIT_2
ADC multimode group regular conversions
are transferred by DMA, one DMA channel for
all ADC instances (DMA of ADC master), in
limited mode (one shot mode): DMA transfer
requests are stopped when number of DMA
data transfers (number of ADC conversions)
is reached. This ADC mode is intended to be
used with DMA mode non-circular. Setting of
DMA mode 2: 2 or 3 (dual or triple mode) half-
words one by one, ADC2&1 then ADC1&3
then ADC3&2.
LL_ADC_MULTI_REG_DMA_LIMIT_3
ADC multimode group regular conversions
are transferred by DMA, one DMA channel for
all ADC instances (DMA of ADC master), in
limited mode (one shot mode): DMA transfer
requests are stopped when number of DMA
data transfers (number of ADC conversions)
is reached. This ADC mode is intended to be
used with DMA mode non-circular. Setting of
DMA mode 3: 2 or 3 (dual or triple mode)
bytes one by one, ADC2&1 then ADC1&3
then ADC3&2.
