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 17−6 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.
