Using MPLAB
®
ICD 3
In-Circuit Debugger
Install the Latest Software
Install the MPLAB® IDE software onto your PC using the MPLAB IDE CD-ROM
or download the software from the MPLAB IDE page of the Microchip web site
(www.microchip.com/MPLAB). Check the latest release notes for additional
information.

➎
Program and Debug
1. Program your device.
2. As a programmer, MPLAB ICD 3 will automatically run your code. As a
debugger, you can run, halt, single step and set breakpoints in your code.

Connect the MPLAB ICD 3 in-circuit debugger to a PC USB port via a USB
cable. If the drivers do not install automatically, then install the drivers as
instructed in: C:\Program Files\Microchip\MPLAB IDE\ICD 3\
Drivers\ddri.htm.
Note: If a USB hub is used, the hub must be powered with its own power supply.

Build Your Project
1. Launch MPLAB IDE.
2. Load your project or use the Project Wizard to create a new one.
4. Build your project based on your configurations and options.
5. Select the MPLAB ICD 3 as either a debugger (Debugger>Select Tool>ICD 3)
or as a programmer (Programmer>Select Programmer>ICD 3).

*Target device must be running with an oscillator for the debugger to function as a debugger.
**If the device has AVDD and AVSS lines, they must be connected for the debugger to operate.

Use the ICD 3 Test Interface Board to verify that the MPLAB ICD 3 is
functioning properly:
1. Disconnect the debugger from the target and 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 “MPLAB ICD 3” on either the Debugger or Programmer menu in
MPLAB IDE.
5. From that menu, select “Settings”, Status tab, then click on Run ICD 3
Test Interface. The status (pass/fail) is displayed in the Output window.

• Do not use multiplexing on PGC/PGD – they are
dedicated for communications to MPLAB ICD 3.
• Do not use pull-ups on PGC/PGD – they will divide the
voltage levels since these lines have 4.7 kΩ pull-down
resistors in MPLAB ICD 3.
• Do not use capacitors on PGC/PGD – they will prevent
fast transitions on data and clock lines during
programming and debug communications.
• Do not use capacitors on MCLR – they will prevent
fast transitions of V PP.
• Do not use diodes on PGC/PGD – they will prevent
bidirectional communication between MPLAB ICD 3 and
the target PIC® MCU.
