JTAG downloading is specified by Atmel, JTAG debugging isn't albeit I
think it has been reverse engineered to some degree.  Given that even
handling the documented way (through their JTAG ICE) already has
proven to have enough potential for serious pitfalls, I doubt though
you'll get much luck in rolling your own JTAG communication.
