Now to the JTAG interface : I am preparing an atmega16 to watch
the JTAG interface of the Atmel's Ice.

How do you think to capture the JTAG traffic(poll, SPI, .)?


So please be patient : things will be published in time but plenty of time isnot
what I have unfortunately (are we all ?).

Well, it sounds realy interresting!
and remember: Release Early, Release Often!

For just dumping a some JTAG bytes it _may_ be oversized :-/
Maybe we _have_ to use the parallel port because in the worst case the JTAG data rate would be 3 * 50 kbit/s (TMS,TDI,TDO)
