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 MPLAB ICD 2 in-circuit debugger.

The modular cable can be either (1) inserted into a matching socket at the target, where

the target device is on the target board (Figure 2-1), or (2) inserted into a standard

adapter/header board combo (available as a Processor Pak), which in then plugged

into the target board (Figure 2-2).

For more on standard communication, see Chapter 10. “Hardware Specification”.

ON-BOARD ICE CIRCUITRY

CAUTION

Do not connect the hardware before installing the software and USB drivers. Also, do

not change hardware connections when the pod or target is powered.

Note: Older header boards used a 6-pin (RJ-11) connector instead of an 8-pin

connector, so these headers may be connected directly to the debugger.
