2: The leakage current on the MCLR pin is strongly dependent on the applied voltage level. The specified levels
3: Negative current is defined as coming out of the pin.

5: The MCLR/Vpp pin may be kept in this range at times other than programming, but this is not recommended.
6: For TTL buffers, the better of the two specifications may be used.
