A.6 STANDARD COMMUNICATION HARDWARE
For standard debugger communication with a target (Section 2.4 “Debugger to
Target Communication”, “Standard ICSP Device Communication“), use an adapter
with an RJ-11 connector.
To use this type of communication with a header board, you may need a device-specific
Processor Pak, which includes an 8-pin connector header board containing the desired
ICE/ICD device and a standard adapter board.
For more on available header boards, see the “Processor Extension Pak and Header
Specification” (DS51292).
A.6.1 Standard Communication
The standard communication is the main interface to the target processor. It contains
the connections to the high voltage (V
PP), VDD sense lines, and clock and data
connections required for programming and connecting to the target devices.
The V
PP high-voltage lines can produce a variable voltage that can swing from 1.8 to
14 volts to satisfy the voltage requirements for the specific emulation processor.
The V
DD sense connection draws current from the target processor.
The clock and data connections are interfaces with the following characteristics:
• Clock and data signals are in High-Impedance mode (even when no power is
applied to the PICkit 3 In-Circuit Debugger/Programmer system)
• Clock and data signals are protected from high voltages caused by faulty target
systems, or improper connections
• Clock and data signals are protected from high current caused from electrical
shorts in prototype or target systems
FIGURE A-1: 6-PIN STANDARD PINOUT
Note: Older header boards used a 6-pin (RJ-11) connector instead of an 6-pin SIL
connector, so these headers may be connected directly to the debugger.
