3.5

V

SS

The power supply ground reference, Vss, must be at the same potential as the 
application circuit.

3.6

OTHER CONSIDERATIONS

Minimize the distance the ICSP signals must travel by placing the ICSP connector as 
close to the application circuit PICmicro MCU as possible. Minimize any cable length 
between the PICkit 2 Microcontroller Programmer and application circuit PICmicro 
MCU. The goal is to keep the ICSP signals within the level and slew rate specifications 
for successful programming.
