RISCTrace Interface

RISCTrace Interface
The RISCTrace tool communicates with the PPC405x3 using the trace interface. It requires
a 20-pin, male 2x10 header connector (3M 3592-6002 or equivalent) located on the target
development board. The layout of the connector is shown in
Figure A-2
and the signals are
described in
Table A-3
. A mapping of PPC405x3 to RISCTrace signals is provided in
Table A-4
. At the board level, the connector should be placed as close as possible to the
processor chip to ensure signal integrity. An index at pin one and a key notch on the same
side of the connector as the index are required.
