Target Adaption of Trace Probe "HSSTP Preprocessor" for ARM ETM/PTM with Samtec-40 |

| LA-7988 | Preproc. for ARM-ETM/HSSTP HF-Flex | |
Target Connector Type
Target Connector Placement
The adaption uses one 40 pin Samtec connector.
We recommend to place the even numbered pins at the PCB border side (flex cable won't be twisted).
Pinout
 Debug Signals
The pinout of the 40 pin Samtec connector optionally includes the debug signals which needs to go to the Debug Cable
(20-pin standard header). The Preprocessors have a 20-pin connector where the user can plug in the Debug Cable.
Alternatively the Debug Cable can be plugged on a separate 20-pin connector on the target. In this case there is no
need to connect the debug signals to the 40 pin Samtec. For better signal quality it is better not to connect them.
The debug signals are VREF-DEBUG, TCK, TMS, TRST-, TDI, TDO, RESET-, DBGRQ, DBGACK, RTCK.
