1. Scan mode is selected (MULTI = 1, SCN = 1), channel group 0 is selected (CH2 = 0), analog
2. When A/D conversion of the first channel (AN0) is completed, the result is transferred into
3. Conversion proceeds in the same way through the third channel (AN2).
4. When conversion of all the selected channels (AN0 to AN2) is completed, the ADF flag is set
5. Steps 2 to 4 are repeated as long as the ADST bit remains set to 1. When the ADST bit is

interrupt is requested at this time.
cleared to 0, A/D conversion stops. After that, if the ADST bit is set to 1, A/D conversion
starts again from the first channel (AN0).
