In scan mode, A/D conversion is to be performed sequentially on the analog inputs of the specified
channels up to four or eight channels.
1. When the ADST bit in ADCSR is set to 1 by software, TPU, TMR, or an external trigger
2. When A/D conversion for each channel is completed, the A/D conversion result is sequentially

input, A/D conversion starts on the first channel in the group. Consecutive A/D conversion on
a maximum of four channels (SCANE and SCANS = B'10) or on a maximum of eight
channels (SCANE and SCANS = B'11) can be selected. When consecutive A/D conversion is
performed on four channels, A/D conversion starts on AN4 when CH3 and CH2 = B'01. When
consecutive A/D conversion is performed on eight channels, A/D conversion starts on AN0
when CH3 = B'0.
