Notes 1. When the internal reference voltage is selected as the reference voltage of the comparator, the internal
reference voltage cannot be used as the target for A/D conversion.
2. Refer to 24.6.3 Internal reference voltage characteristics.

Note The internal reference voltage cannot be simultaneously used by the A/D converter and the comparator; only one
of them must be selected.
