1. Disconnect the debugger from the target and the PC.
2. Connect the ICD 3 test interface board to the debugger using the modular cable.
3. Connect the debugger to the PC.
4. Select the MPLAB ICD 3 in-circuit debugger as either a debugger or programmer
in MPLAB IDE.
5. MPLAB IDE will invoke and run the complete self-test and give you a status
(pass/fail).
10.8 TARGET BOARD CONSIDERATIONS
The target board should be powered according to the requirements of the selected
device (2.0V-5.5V) and the application.
The debugger does sense target power. There is a 10KΩ load on V
DD_TGT.
Depending on the type of debugger-to-target communications used, there will be some
considerations for target board circuitry:
• Section 2.5.2 “Target Connection Circuitry”
• Section 2.5.5 “Circuits That Will Prevent the Debugger From Functioning”
