Negative injection disturbs the analog performance of the device. In particular, it induces leakage currents

throughout the device including the analog inputs. To avoid undesirable effects on the analog functions,

care must be taken:

- Analog input pins must have a negative injection less than 0.8 mA (assuming that the impedance of the

analog voltage is lower than the specified limits)

- Pure digital pins must have a negative injection less than 1.6 mA. In addition, it is recommended to inject

the current as far as possible from the analog input pins.
