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 may be measured at different input
voltages.
2: Negative current is defined as current sourced by the pin.
3: Parameter is characterized but not tested.
