In scan mode, A/D conversion is to be performed sequentially on the specified channels (four
channels maximum). The operations are as follows.
1. When the ADST bit is set to 1 by software, timer conversion start trigger, or external trigger
2. When A/D conversion for each channel is completed, the result is sequentially transferred to
3. When conversion of all the selected channels is completed, the ADF flag is set to 1. If the
4. Steps 2 to 3 are repeated as long as the ADST bit remains set to 1. When the ADST bit is

input, A/D conversion starts on the first channel in the group (AN0 when CH3 = 0 and CH2 =
0, AN4 when CH3 = 0 and CH2 = 1, AN8 when CH3 = 1 and CH2 = 0, or AN12 when CH3 =
1 and CH2 = 1).

cleared to 0, A/D conversion stops and the A/D converter enters the wait state. After that,
when the ADST bit is set to 1, conversion of the first channel in the group starts again.
