Note 1: Input only.

2: Only when pin is configured for external MCLR.

3: VDDT is the supply voltage of the Analog Front-End section (PIC16F639 only). VDDT is treated as VDD in

this document unless otherwise stated.

4: VSST is the ground reference voltage of the Analog Front-End section (PIC16F639 only). VSST is treated

as VSS in this document unless otherwise stated.
