SETTING UP THE TARGET BOARD
3.4.1
Using Production Devices
For 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 the
PICkit 3 programmer/debugger to perform emulation with it. Consult the device data
sheet 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 chosen
for the debugger. For connection information, see Section 2.3 “Debugger to Target
Communication” , “Standard ICSP Device Communication”.
3.4.2
Using ICE Devices
For ICE devices, an ICE header board is required. The header board contains the
hardware necessary to emulate a specific device or family of devices. For more
information on ICE headers, see the “ Header Board Specification” (DS51292).
Note:
In the future, ICD header boards with ICD devices ( Device -ICD) may be
used.
A transition socket is used with the ICE header to connect the header to the target
board. Transition sockets are available in various styles to allow a common header to
be connected to one of the supported surface mount package styles. For more
information on transition sockets, see the “Transition Socket Specification” (DS51194).
Header board layout will be different for headers or processor extension packs. For
connection information, see Section 2.3 “Debugger to Target Communication” ,
“Standard ICSP Device Communication”.
3.4.3
Using an ICD Header
All Baseline and some Mid-Range PIC microcontrollers require a special –ICD device
mounted on a debug header circuit board to enable the debugging feature. For a list of
these devices and the required ICD header board part number, please see the “ Header
Board Specification ” (DS51292). The Header Board Specification is included on the
PICkit 3 CD-ROM, and is available online at www.microchip.com.
Each ICD header board comes with the necessary –ICD device, and is used on the
target board instead of the production microcontroller. However, most header boards
have an RJ-11 debug connector which requires the AC164110 RJ-11 to ICSP adapter
kit to connect it to PICkit 3. Figure 3-2 illustrates using the AC162061 ICD Header for
the PIC18F45K20 with the AC164110 adapter kit and Low Pin Count Demo Board.
