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.

Negative current is defined as current sourced by the pin.

Only available on 44-pin devices.

When used as general purpose inputs, the RC4 and RC5 thresholds are referenced to VUSB instead of VDD.

Refer to Table 10-2 for pin tolerance levels.
