TMDSEMU110-U: What Is the correct mating connector to the CTI-20 Debug Interface and Auxiliary Debug Interface?

Mike Allette

Part Number: TMDSEMU110-U

Tool/software:

Hi,

Looking at the XDS110 Debug Probe User's Guide, it says Pin 7 of the AUX connection is keyed. However, when I look at the JTAG Connectors and Pinout document, it says that Pin 6 is keyed. Which is correct?

Also, what is the actual part number for the 20-pin debug cable and the14-pin auxiliary cable that comes with the TMDSEMU110-U package?

The JTAG Connectors and Pinout table is for primary debug interfaces only and lists out headers with dedicated JTAG functionality. The Connector you are referring to is an Auxiliary connector that does not have JTAG functionality on it but instead provides additional complementary pins for JTAG usage.
