23.2.6.1 Single-Channel Single-Conversion Mode
A single channel is sampled and converted once. The ADC result is written to the ADC12MEMx defined
by the CSTARTADDx bits. Figure 23-6 shows the flow of the single-channel, single-conversion mode.
When ADC12SC triggers a conversion, successive conversions can be triggered by the ADC12SC bit.
When any other trigger source is used, ENC must be toggled between each conversion.
