Caution For pins which also function as port pins, do not perform the following operations during A/D
conversion. If these operations are performed, the total error ratings cannot be kept (except for LCD
segment output alternate-function pin).
(1) Rewrite the output latch which the pin is used as a port pin.
(2) Change the output level of the pin used as an output pin, even if it is not used as a port pin.
