MPLAB ICD 3 In-Circuit Debugger User's Guide

MPLAB ® ICD 3 In-Circuit Debugger User’s Guide3.4 CONNECTING THE TARGETA connection is built-in to select the type of communication with the target. SeeSection 2.4 “Debugger To Target Communication” for more details and a diagram.1. Plug in the USB/power cable if not already connected.2. Attach the communication cable(s) between debugger and target.FIGURE 3-1:INSERT COMMUNICATIONS AND USB/POWER CABLESMPLAB ® ICD 3CommunicationsCable1From Target2USB/PowerFrom PC3.5 SETTING UP THE TARGET BOARDThe target must be set up for the type of target device to be used.3.5.1 Using Production DevicesFor production devices, the debugger may be connected directly to the target board.The device on the target board must have built-in debug circuitry in order for theMPLAB ICD 3 in-circuit debugger to perform emulation with it. Consult the device datasheet to see if the device has the needed debug circuitry, i.e., it should have a“Background Debugger Enable” Configuration bit.Note:In the future, devices with circuitry that support ICD may be used.The target board must have a connector to accommodate the communications chosenfor the debugger. For connection information, see Section 2.4 “Debugger To TargetCommunication”, “Standard ICSP Device Communication”.3.5.2 Using ICE DevicesFor ICE devices, an ICE header board is required. The header board contains thehardware necessary to emulate a specific device or family of devices. For moreinformation on ICE headers, see the “Header Board Specification” (DS51292).Note:In the future, ICD header boards with ICD devices (Device-ICD) may beused.DS51766A-page 22© 2008 Microchip Technology Inc.
