ADC10 Operation

ADC10
Repeat-Sequence-of-Channels Mode
A sequence of channels is sampled and converted repeatedly. The sequence
begins with the channel selected by INCHx and decrements to channel A0.
Each ADC result is written to ADC10MEM. The sequence ends after
conversion of channel A0, and the next trigger signal re-starts the sequence.
Figure 18−8 shows the repeat-sequence-of-channels mode.
