1. ADC accuracy vs. negative injection current: Injecting negative current on any of the 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 IINJ(PIN) and

IINJ(PIN) in Section 9.3.6 does not affect the ADC accuracy.
