Continuous Conversion Mode

In the continuous conversion mode, A/D conversion is performed sequentially from the
start channel to the end channel. When A/D conversion for the end channel is
terminated, it is continued after returning to the start channel.
Setting of Continuous Conversion Mode
Operating the 8-/10-bit A/D converter in the continuous conversion mode requires the setting shown in
Figure 18.5-2 .
