DEBUGGER USER’S GUIDE

Chapter 1. Overview

1.1 INTRODUCTION

An overview of the MPLAB ICD 3 in-circuit debugger system is given.

• MPLAB ICD 3 In-Circuit Debugger Defined

• How the MPLAB ICD 3 In-Circuit Debugger Helps You

• MPLAB ICD 3 In-Circuit Debugger Kit Components

• Device and Feature Support

1.2 MPLAB ICD 3 IN-CIRCUIT DEBUGGER DEFINED

The MPLAB ICD 3 in-circuit debugger is an in-circuit debugger that is controlled by a

PC running MPLAB IDE (v8.15 or greater) software on a Windows®platform. The

MPLAB ICD 3 in-circuit debugger is an integral part of the development engineer's

toolsuite. The application usage can vary from software development to hardware

integration.

The MPLAB ICD 3 in-circuit debugger is a complex debugger system used for

hardware and software development of Microchip PIC®microcontrollers (MCUs) and

dsPIC®Digital Signal Controllers (DSCs) that are based on In-Circuit Serial

Programming™ (ICSP™) and Enhanced In-Circuit Serial Programming 2-wire serial

interfaces.

The debugger system will execute code like an actual device because it uses a device

with built-in emulation circuitry, instead of a special debugger chip, for emulation. All

available features of a given device are accessible interactively, and can be set and

modified by the MPLAB IDE interface.

The MPLAB ICD 3 debugger was developed for emulating embedded processors with

rich debug facilities which differ from conventional system processors in the following

aspects:

• Processors run at maximum speeds

• Capability to incorporate I/O port data input

In addition to debugger functions, the MPLAB ICD 3 in-circuit debugger system also

may be used as a development programmer.

1.3 HOW THE MPLAB ICD 3 IN-CIRCUIT DEBUGGER HELPS YOU

The MPLAB ICD 3 in-circuit debugger system allows you to:

• Debug your application on your own hardware in real time

• Debug with hardware breakpoints

• Debug with software breakpoints

• Set breakpoints based on internal events

• Monitor internal file registers

• Emulate full speed

• Program your device

1.4 MPLAB ICD 3 IN-CIRCUIT DEBUGGER KIT COMPONENTS

The components of the MPLAB ICD 3 in-circuit debugger system kit are:

1. MPLAB ICD 3 with indicator lights

2. USB cable to provide communications between the debugger and a PC and to

provide power to the debugger

3. Cable (also MPLAB ICD 2 compatible) to connect the MPLAB ICD 3 to a header

module or target board

DEBUGGER USER’S GUIDE

Chapter 2. Theory of Operation

2.1 INTRODUCTION

A simplified description of how the MPLAB ICD 3 in-circuit debugger system works is

provided here. It is intended to provide enough information so a target board can be

designed that is compatible with the debugger for both emulation and programming

operations. The basic theory of in-circuit emulation and programming is described so

that problems, if encountered, are quickly resolved.

• MPLAB ICD 3 In-Circuit Debugger vs. MPLAB ICE 2000/4000 In-Circuit

Emulators

• MPLAB ICD 3 In-Circuit Debugger vs. MPLAB ICD 2 Debugger

• Debugger To Target Communication

• Communication Connections

• Debugging with the Debugger

• Requirements For Debugging

• Programming with the Debugger

• Resources Used by the Debugger

2.2 MPLAB ICD 3 IN-CIRCUIT DEBUGGER VS. MPLAB ICE 2000/4000

IN-CIRCUIT EMULATORS

The MPLAB ICD 3 in-circuit debugger system is a next generation In-Circuit Debugger

(ICD) system. It differs from classical in-circuit emulator systems (e.g., MPLAB ICE

2000/4000) in a single, but important way: the production device and emulation device

are the same.

This is a great benefit since differences (errata) between the production silicon and

emulation silicon are eliminated. Additionally, as devices continue to operate at faster

speeds, traditional emulator systems present bottlenecks caused by internal busses

that must be carried off-chip to external memories and cannot offer full speed

emulation.

Another significant benefit is that there is no lead time between production silicon and

emulation silicon. Further, a problem encountered on a production board can be easily

debugged without having to install transition sockets and dealing with complicated

cabling systems and setups to have access to the application.

2.3 MPLAB ICD 3 IN-CIRCUIT DEBUGGER VS. MPLAB ICD 2 DEBUGGER

The MPLAB ICD 3 in-circuit debugger system is similar in function to the MPLAB ICD

2 in-circuit debugger system, but surpasses it in speed and functionality. The MPLAB

ICD 3 also:

• Features USB high speed

• Is USB powered

• Is a hardware accelerator

• Provides a programmable voltage power supply

• Eliminates the RS-232 port

• Includes a diagnostic self-test interface board

MPLAB®ICD 3 In-Circuit Debugger User’s Guide

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”.

FIGURE 2-1: STANDARD DEBUGGER SYSTEM – DEVICE WITH

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.
