Cautions For pins which have alternate functions as port output (See 3.1.1 Normal operating mode pins,
(1) Port Pins), do not execute the following operations during A/D conversion. If performed,
then the general error standards cannot be maintained during A/D conversion.
<1> If it is used as a port, rewriting the output latch of its output.
<2> Even if it is not used as a port, changing the output level of pins used as outputs.
