    STMicroelectronics currently only supports the SWD interface. JTAG interfaces are only available from third party companies.

    Does it answer your question?

    Tends to be expensive to implement, test and support. Use commercial solutions.​

    Segger J-Link documentation mentions something like multi-drop SWD interface and identification or selection of targets on the wire. It's not clear is this a feature of a Segger product or not. I've tried to get more details on their forum, without success.
