analog input pins should be avoided as this significantly reduces the accuracy of the
conversion being performed on another analog input. It is recommended to add a Schottky
diode (pin to ground) to standard analog pins which may potentially inject negative current.
Any positive injection current within the limits specified for I
port pin characteristics section does not affect the ADC accuracy.
