10-pin Plug-of-Nails™ “No Legs” connector to 20-pin 0.050″ pitch ribbon connector suitable for ULINK2 and similar debuggers that use the Samtec FTSH-110-01 style micro-header.
But it has a 0.05" pitch ribbon cable connector, not a 0.1" pitch, and I am not free to use the pins how I like because I am constrained by the connections of the device it plugs into.
The Tag Connect cable footprint is much smaller than an equivalent 0.1' pitch header. You are free to allocate pins as you choose; they do not need to mirror the same pin numbers as a previous design as the connectors are quite different. If you do need to maintain the same pin numbers then you might have to rearrange pins as you suggest. Most of our customers are designing the Tag Connect footprint into a completely new PCB design so this is not an issue.
