Note
Overroll error excluding quantization error (
±
1/2 LSB). It is indicated as a ratio to the full-scale value.
Caution
For pins that also function as port pins (refer to 3.1 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 while 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.
