Operation of Continuous Conversion Mode
In the continuous conversion mode, the analog inputs set by the ANS and ANE bits are sequentially
converted, the analog input set by the ANE bit is resumed at the end of conversion of the termination
channel set by the ANS bit, and the A/D conversion operation is continued. When the start channel and the
termination channel are same (ANS = ANE), the conversion of only channels specified by the ANS is
repeated. For the operation in the continuous conversion mode, the setting as shown in Figure 19.4-2 is
necessary.
