Section 3.6.4

A/D conversion

enable/prohibit

specification

Specify whether A/D conversion is enabled or disabled per channel.

By prohibiting the conversion for the channels which are not used, the sampling time

can be shortened.

Section 3.6.2

Can set the analog input range per channel to change the I/O conversion

characteristics.
