Precautions about the AD Converter
outside this range is applied to one of the analog input pins, the converted value on that pin becomes uncertain,
and converted values on other pins will also be affected.
to execute AD conversion, input/output instructions at all other pins (ports) must not be executed. If they are
executed, there is the possibility that the accuracy of AD conversion may deteriorate. This also applies to pins
other than analog input pins; if one pin receives inputs or generates outputs, noise may occur and its adjacent
pins may be affected by that noise.
of the analog input source, the more susceptible it becomes to noise. Therefore, make sure the output impedance
of the signal source in your design is 5 kΩ or less. It is recommended that a capacitor be attached externally.
Analog input pins (AIN0 through AIN15) should be used at voltages from VAREF to VSS. If any voltage
Analog input pins (AIN0 to AIN15) are also used as input/output ports. In using one of analog input pins (ports)
The internal equivalent circuit of the analog input pins is shown in Figure 20-5. The higher the output impedance
