Section 22 A/D Converter
22.4.2
In scan mode, A/D conversion is to be performed sequentially on the analog inputs of the specified
channels up to four or eight*
scan mode where A/D conversion is repeatedly performed and one-cycle scan mode where A/D
conversion is performed for the specified channels for one cycle.

input, A/D conversion starts on the first channel in the specified channel group. Consecutive
A/D conversion on a maximum of four channels (SCANE and SCANS = B'10) or on a
maximum of eight channels*
consecutive A/D conversion is performed on four channels, A/D conversion starts on AN0
when CH3 and CH2 of unit 0 = B’00, on AN4 when CH3 and CH2 of units 0 and 1 = B'01.
