Note 1:
In RC oscillator configuration, the OSC1/CLKI pin is a Schmitt Trigger input. It is not recommended that the 
PIC
®
 device be driven with an external clock while in RC mode.
2:
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 may be measured at different input 
voltages.
3:
Negative current is defined as current sourced by the pin.
