Note 1:
The leakage current on the MCLR pin is strongly dependent on the applied voltage level. The specified 
levels represent normal operating conditions. Higher leakage current can be measured at different input 
voltages.
2:
Negative current is defined as current sourced by the pin.
3:
See the 
Pin Diagrams
 section for the 5V tolerant I/O pins.

tested.
6:
Digital 5V tolerant pins cannot tolerate any “positive” input injection current from input sources > 5.5V.
7:
Non-zero injection currents can affect the ADC results by approximately 4-6 counts. 
8:
Any number and/or combination of I/O pins not excluded under I
ICL
 or I
ICH
 conditions are permitted 
provided the mathematical “absolute instantaneous” sum of the input injection currents from all pins do not 
exceed the specified limit. Characterized but not tested.
