23.2.6.4 Repeat-Sequence-of-Channels Mode
A sequence of channels is sampled and converted repeatedly. The ADC results are written to the
conversion memories starting with the ADC12MEMx defined by the CSTARTADDx bits. The sequence
ends after the measurement of the channel with a set EOS bit, and the next trigger signal re-starts the
sequence. Figure 23-9 shows the repeat-sequence-of-channels mode.
