3.4.1 Standard Communication
The emulator system can be configured to use the standard connection for communi-
cating debug and programming instructions to the target. This 6-pin connection is the
same one used by other Microchip in-circuit debuggers.
The standard driver board is plugged into the emulator pod to configure the system for
communication with the target. The modular cable can be either (1) inserted into a
matching socket at the target, where the target device is on the target board, as shown
in Figure 3-2, or (2) inserted into a standard adapter/debug header combo – available
as a Processor Pak – which is then plugged into the target board, as shown in
Figure 3-3.
A debug header is a small circuit board with an -ME2/-ICE/-ICD device mounted onto
it. These devices provide debug functionality for production devices that (1) do not have
on-board debug circuitry or (2) cannot afford to lose I/O pins for debugging. For more
on debug headers, see the “Debug Header Specification“ (in “Recommended
Reading”).
To see the debug features of a device versus those of a debug header, see the Devel-
opment Tools Selector on the Development Tools home page on the Microchip website
(http://www.microchip.com/dts).
For more on the hardware, see Section 12.5 “Standard Communication Hardware”.

CIRCUITRY
Note: Older debug headers used a 6-pin (RJ-11) connector instead of an 8-pin
connector, so these headers may be connected directly to the emulator.
