  *         (functions with prefix "REG").

  * @note   The setting of these parameters by function @ref LL_ADC_REG_Init()
264
  *         is conditioned to ADC state:
265
  *         ADC instance must be disabled.
266
  *         This condition is applied to all ADC features, for efficiency
267
  *         and compatibility over all STM32 families. However, the different
268
  *         features can be set under different ADC state conditions
269
  *         (setting possible with ADC enabled without conversion on going,
270
  *         ADC enabled with conversion on going, ...)
271
  *         Each feature can be updated afterwards with a unitary function
272
  *         and potentially with ADC in a different state than disabled,
273
  *         refer to description of each function for setting
274

1623
  *         - ADC low power mode "auto wait": Dynamic low power mode,
1624
  *           ADC conversions occurrences are limited to the minimum necessary
1625
  *           in order to reduce power consumption.
1626
  *           New ADC conversion starts only when the previous
1627
  *           unitary conversion data (for ADC group regular)
1628
  *           has been retrieved by user software.
1629
  *           In the meantime, ADC remains idle: does not performs any
1630
  *           other conversion.
1631
  *           This mode allows to automatically adapt the ADC conversions
1632
  *           triggers to the speed of the software that reads the data.
1633
  *           Moreover, this avoids risk of overrun for low frequency
1634
  *           applications.
1635
  *           How to use this low power mode:
1636
  *           - Do not use with interruption or DMA since these modes
1637
  *             have to clear immediately the EOC flag to free the
1638
  *             IRQ vector sequencer.
1639
  *           - Do use with polling: 1. Start conversion,
1640
  *             2. Later on, when conversion data is needed: poll for end of
1641
  *             conversion  to ensure that conversion is completed and
1642
  *             retrieve ADC conversion data. This will trig another
1643
  *             ADC conversion start.
1644
  *         - ADC low power mode "auto power-off" (feature available on
1645
  *           this device if parameter LL_ADC_LP_MODE_AUTOOFF is available):
1646
  *           the ADC automatically powers-off after a conversion and
1647
  *           automatically wakes up when a new conversion is triggered
1648
  *           (with startup time between trigger and start of sampling).
1649
  *           This feature can be combined with low power mode "auto wait".
1650
  * @note   With ADC low power mode "auto wait", the ADC conversion data read
1651
  *         is corresponding to previous ADC conversion start, independently
1652
  *         of delay during which ADC was idle.
1653
  *         Therefore, the ADC conversion data may be outdated: does not

2243
  *           rank of each channel is fixed by channel HW number
2244
  *           (channel 0 fixed on rank 0, channel 1 fixed on rank1, ...).
2245
  * @note   On this STM32 serie, ADC group regular sequencer is
2246
  *         not fully configurable: sequencer length and each rank
2247
  *         affectation to a channel are fixed by channel HW number.
2248
  * @note   Depending on devices and packages, some channels may not be available.

2250
  * @note   On this STM32 serie, to measure internal channels (VrefInt,
2251
  *         TempSensor, ...), measurement paths to internal channels must be
2252
