Precautions about AD Converter
outside this range is applied to one of the analog input pins, the converted value on that pin becomes uncertain.
The other analog input pins also are affected by that.
to execute AD conversion, do not execute input/output instructions for all other ports. This is necessary to prevent
the accuracy of AD conversion from degrading. Not only these analog input shared pins, some other pins may
also be affected by noise arising from input/output to and from adjacent pins.
of the analog input source, more easily they are susceptible to noise. Therefore, make sure the output impedance
of the signal source in your design is 5 kΩ or less. Toshiba also recommends attaching a capacitor external to the
chip.
Make sure the analog input pins (AIN0 to AIN5) are used at voltages within VDD to VSS. If any voltage
The analog input pins (AIN0 to AIN5) are shared with input/output ports. When using any of the analog inputs
