Note 1: Any references to PORTA, RAn, TRISA and TRISAn refer to GPIO, GPn, TRISIO and TRISIOn, respectively.
2: V
DDT is the supply voltage of the Analog Front-End section (PIC16F639 only). VDDT is treated as VDD in
this document unless otherwise stated.
3: VSST is the ground reference voltage of the Analog Front-End section (PIC16F639 only). VSST is treated
as V
SS in this document unless otherwise stated.
