and are not tested.
In RC oscillator configuration, the OSC1/CLKI pin is a Schmitt Trigger input. It is not recommended to use an
external clock in RC mode.
Negative current is defined as current sourced by the pin.
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.
