0 = DMAx is disabled and data transfer requests are disregarded.
1 = DMAx is enabled and initiates a data transfer upon receipt of a request from the
DLE—DMAx Loop Enable
0 = DMAx reloads the original Start Address and is then disabled after the End
Address data is transferred.

When using the DMA_ADC to perform conversions on multiple ADC inputs,
the Analog-to-Digital Converter must be configured for SINGLE-SHOT mode.
If the ADC_IN field in the DMA_ADC Control Register is greater than 000b,
the ADC must be in SINGLE-SHOT mode.
CONTINUOUS mode operation of the ADC can only be used in conjunction
with DMA_ADC if the ADC_IN field in the DMA_ADC Control Register is re-
set to 000b to enable conversion on ADC Analog Input 0 only.
