Appendix A Electrical Characteristics
This device contains circuitry protecting against damage due to high static voltage or electrical fields;
however, it is advised that normal precautions be taken to avoid application of any voltages higher than
maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused
inputs are tied to an appropriate logic voltage level (for instance, either V
pull-up resistor associated with the pin is enabled.

All functional non-supply pins except RESET are internally clamped to V
Power supply must maintain regulation within operating V
conditions. If positive injection current (V
result in external power supply going out of regulation. Ensure external V
injection current. This will be the greatest risk when the MCU is not consuming power. Examples are: if no system clock is
present, or if the clock rate is very low (which would reduce overall power consumption).
Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate
