(1) _{Data based on characterisation results, not tested in production.}
(2) _{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 I_INJ(PIN) and ΣI_INJ(PIN) in the I/O
port pin characteristics section does not affect the ADC accuracy.
