For devices where you need most of the pins Nexus can't be
used.
Not wholly true. Trace needs lots of pins, yes.
Basic debug only needs JTAG layers. Same with ARM:
but Nexus trace has more parallel wiring options.
There was some other Nexus option that chewed up
pins too. Emphasis: option.
The Nexus connector on my AT32UC3C-EK board uses 16 pins while the JTAG
connector uses 6 pins.
If I had a device with over 200 pins I may not care but a device with
144 pins or less, no way.
