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.
