23.2.6.2 Sequence-of-Channels Mode
A sequence of channels is sampled and converted once. The ADC results are written to the conversion
memories starting with the ADCMEMx defined by the CSTARTADDx bits. The sequence stops after the
measurement of the channel with a set EOS bit. Figure 23-7 shows the sequence-of-channels mode.
When ADC12SC triggers a sequence, successive sequences can be triggered by the ADC12SC bit. When
any other trigger source is used, ENC must be toggled between each sequence.
