CONNECTING THE TARGET
A connection is built-in to select the type of communication with the target. See
Section 2.4 “Debugger To Target Communication” for more details and a diagram.
Section 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.

SETTING UP THE TARGET BOARD
The target must be set up for the type of target device to be used.
3.5.1
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
MPLAB ICD 3 in-circuit 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.

The target board must have a connector to accommodate the communications chosen
for the debugger. For connection information, see Section 2.4 “Debugger To Target
Communication”, “Standard ICSP Device Communication”.

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).
