RISCWatch and RISCTrace Interfaces
This appendix summarizes the interface requirements between the PPC405x3 and the
RISCWatch and RISCTrace tools.
The requirement for separate JTAG and trace connectors is being replaced with a single
Mictor connector to improve the electrical and mechanical characteristics of the interface.
Pin assignments for the Mictor connector are included in the signal-mapping tables.
RISCWatch Interface
The RISCWatch tool communicates with the PPC405x3 using the JTAG and debug
interfaces. It requires a 16-pin, male 2x8 header connector located on the target
development board. The layout of the connector is shown in
described in
Table
processor chip to ensure signal integrity. Position 14 is used as a connection key and does
not contain a pin.
