Section 38 A/D Converter

Typical operations when three channels (AN0 to AN2) are selected in multi mode are described
below. Figure 38.3 shows a timing diagram for this example.
1. Select multi mode as the operating mode (MDS[1:0] = 10) and AN0 to AN2 as the analog
input channels (CH[2:0] = 010). Then start A/D conversion (ADST = 1).
2. A/D conversion of the first channel (AN0) starts. When A/D conversion ends, the result is
transferred into ADDRA. Next, the second channel (AN1) is selected automatically and A/D
conversion starts.
3. A/D conversion proceeds in the same way up to the third channel (AN2).
4. When A/D conversion of all selected channels (AN0 to AN2) is completed, the ADF bit is set
to 1, the ADST bit is cleared to 0, and A/D conversion stops.
If the ADIE bit is set to 1 at this time, an ADI interrupt is generated after A/D conversion ends.
