2.3 DEBUGGER TO TARGET COMMUNICATION
The debugger system configurations are discussed in the following sections.
2.3.1 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 MPLAB ICD 2 In-Circuit 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 B. “Hardware Specification” .

ON-BOARD ICE CIRCUITRY
CAUTION
Communication Failure.
Do not connect the hardware before installing the software and
USB drivers.
CAUTION
Debugger or Target Damage.
Do not change hardware connections while the pod or target is
powered.
Note: Older header boards used a 6-pin (RJ-11) modular connector instead of an
8-pin connector, so these headers may be connected directly to the
debugger.
