2.4 DEBUGGER TO TARGET COMMUNICATION
The debugger system configurations are discussed in the following sections.
Standard ICSP Device Communication
The debugger system can be configured to use standard ICSP communication for both
programming and debugging functions. This 6-pin connection is the same one used by
the older PICkit 2 Development Programmer/Debugger.
The modular cable can be inserted into either:
• a matching socket at the target, where the target device is on the target board
(Figure 2-1), or
• a standard adapter/header board combo (available as a Processor Pak), which is
then plugged into the target board (Figure 2-2).
For more on standard communication, see Appendix A. “Hardware Specification”.

ON-BOARD ICE CIRCUITRY
CAUTION
Install the software before making any hardware connections, i.e., do NOT connect
the hardware before installing the software and USB drivers.
Do NOT change hardware connections when the PICkit 3 and/or the target are
powered.
Note: Older header boards used a 6-pin modular connector instead of an 6-pin
single in-line connector, so these headers can be connected to the
debugger using an AC164110 ICSP adapter.
