ADC10 Operation

ADC10
Sequence-of-Channels Mode
A sequence of channels is sampled and converted once. The sequence
begins with the channel selected by INCHx and decrements to channel A0.
Each ADC result is written to ADC10MEM. The sequence stops after
conversion of channel A0. Figure 18−6 shows the sequence-of-channels
mode. When ADC10SC triggers a sequence, successive sequences can be
triggered by the ADC10SC bit . When any other trigger source is used, ENC
must be toggled between each sequence.
