NOTES:
1. Permanent damage can occur if maximum ratings are exceeded. Exposure to voltages or currents in excess
of recommended values affects device reliability. Device modules may not operate normally while being ex-
posed to electrical extremes.
2. Although sections of the device contain circuitry to protect against damage from high static voltages or elec-
trical fields, take normal precautions to avoid exposure to voltages higher than maximum-rated voltages.

4. All functional non-supply pins are internally clamped to VSS. All functional pins except EXTAL and XFC are
internally clamped to VDD. Does not include QADC pins (refer to Table A-11). 5. Input must be current limited to the value specified. To determine the value of the required current-limiting
resistor, calculate resistance values for positive and negative clamp voltages, then use the larger of the two
values.
6. Power supply must maintain regulation within operating VDD range during instantaneous and operating max-
imum current conditions.
7. This parameter is periodically sampled rather than 100% tested.
8. Total input current for all digital input-only and all digital input/output pins must not exceed 10 mA. Exceeding
this limit can cause disruption of normal operation.
