PICkit 3 Connector Pinout
•
Do not use mulitplexing on PGC/PGD
–
they are
dedicated for communications to PICkit 3.
•
Do not use pull-ups on PGC/PGD
–
they will divide the
voltage levels since these lines have 4.7 k
Ω
pull-down
resistors in PICkit 3.
•
Do not use capacitors on PGC/PGD
–
they will prevent
fast transitions on data and clock lines during
programming and debug communications.

•
Do not use diodes on PGC/PGD
–
they will prevent
bidirectional communication between PICkit 3 and the
