Pin numbers are for PQFP packages.

For the PowerPC 403 and 604, the TDI pullup should be 10KΩ.
3
For the PowerPC 403, TRST and HRESET are Noconnects and the HALT line is connected to header pin 11
instead of SRESET.
4
The +3.3V signal is source from the target development board and is used as a reference signal. It should be
the power signal being supplied to the processor. It does not supply power to the HP processor probe.
5
This 1KΩ series resistor provides short circuit current limiting protection only. If the resistor is present, it
should be 1KΩ or less.
6
For the PowerPC 602 and 604 processors, this line is called CKSTP_OUT.
7
If the target development board does not use this signal, the board must have a 1KΩ pulldown resistor
connected to this pin. This signal allows the HP processor probe to force the processor into soft stop mode.
