ADC10 Operation
18-10
ADC10
Single-Channel Single-Conversion Mode
A single channel selected by INCHx is sampled and converted once. The ADC
result is written to ADC10MEM. Figure 18−5 shows the flow of the
single-channel, single-conversion mode. When ADC10SC triggers a
conversion, successive conversions can be triggered by the ADC10SC bit.
When any other trigger source is used, ENC must be toggled between each
conversion.
