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. The effect of negative injection current on robust
pins is specified in
Any positive injection current within the limits specified for I
affect the ADC accuracy.
