Having picked through the spec to check this, this all looks good. With our only review notes (stylistic) fixed, please rebase this on main and we'll get it merged.
We checked the specification where it talks about how to step through the various state machines, and per the spec, those 8 high cycles are required:

This all LGTM, merging once it's re-rebased on main (apologies, we just merged #1941, hence). Thank you for the contribution!
Edit: In the interests of seeing this merged, we have done that final rebase for you and will presently merge this PR.
… and is jtag by default

Detailed description
For what i could see, it still works with RP2040 and older Arm chips i have (STM32F1/GD32F3)
Tested on a chip with both Jtag & SWD/Default jtag + Debug Protocol v3, it works with the change, doesnt without
NB: Not completely sure the 8 trailer '1' bits are really needed, it works fine with, was there in the demo code
