2.1 INTRODUCTIONMPLAB ® ICD 3 IN-CIRCUITDEBUGGER USER’S GUIDEChapter 2. Theory of OperationA simplified description of how the MPLAB ICD 3 in-circuit debugger system works isprovided here. It is intended to provide enough information so a target board can bedesigned that is compatible with the debugger for both emulation and programmingoperations. The basic theory of in-circuit emulation and programming is described sothat problems, if encountered, are quickly resolved.• MPLAB ICD 3 In-Circuit Debugger vs. MPLAB ICE 2000/4000 In-CircuitEmulators• 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 Debugger2.2 MPLAB ICD 3 IN-CIRCUIT DEBUGGER VS. MPLAB ICE 2000/4000IN-CIRCUIT EMULATORSThe 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 ICE2000/4000) in a single, but important way: the production device and emulation deviceare the same.This is a great benefit since differences (errata) between the production silicon andemulation silicon are eliminated. Additionally, as devices continue to operate at fasterspeeds, traditional emulator systems present bottlenecks caused by internal bussesthat must be carried off-chip to external memories and cannot offer full speedemulation.Another significant benefit is that there is no lead time between production silicon andemulation silicon. Further, a problem encountered on a production board can be easilydebugged without having to install transition sockets and dealing with complicatedcabling systems and setups to have access to the application.2.3 MPLAB ICD 3 IN-CIRCUIT DEBUGGER VS. MPLAB ICD 2 DEBUGGERThe MPLAB ICD 3 in-circuit debugger system is similar in function to the MPLAB ICD2 in-circuit debugger system, but surpasses it in speed and functionality. The MPLABICD 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© 2008 Microchip Technology Inc.
