I'm not sure that CMSIS-DAP needs to be put in backticks? https://arm-software.github.io/CMSIS_5/DAP/html/index.html just uses it as a regular word.

Backticks are typically added for literal identifiers (like a protocol name or configuration option) that might appear in code or logs. I put it in backticks because it's the name of a protocol, but you could also make the argument that you're describing the protocol more generally if you really want to remove the backticks.
