1. Not 100% tested, guaranteed by design characterization.
2. This specification is not valid for outputs which are switched to open drain mode. In this case the respective output will float
3. Port 5 leakage values are granted for not selected A/D Converter channel. One channels is always selected (by default,
4. The leakage of P2.0 is higher than other pins due to the additional logic (pass gates active only in specific test modes)
5. Overload conditions occur if the standard operating conditions are exceeded, i.e. the voltage on any pin exceeds the
6. This specification is only valid during Reset, or during Hold- or Adapt-mode. Port 6 pins are only affected, if they are used
7. The maximum current may be drawn while the respective signal line remains inactive.
8. The minimum current must be drawn in order to drive the respective signal line active.
9. The power supply current is a function of the operating frequency (f
