Hi All!

To clarify a bit further... The 1-wire debug interface is going to be used
on the newer smaller devices, ATtiny and ATMega8 and downwards. The Jtag
will still be the debug interface on the larger devices. I.E. the ATmega16
and upwards.

Not quite sure what seminar you've attended, but the one I was at didn't
mention anything about phasing out the JTAGIce. On the contrary, during the
lunch when I spoke to one of the senior technical engineers at Atmel here in
Trondheim, said that they were going to release a version of the JTAGICE
with USB interface.

Best Regards

They aren't removing jtag. You will still be able to do the boundary scan
and programming with the 4 pin interface as today. They are going to add a
1-wire debug interface using the reset pin. It wasn't clear if you will
still be able to use the 4 pin debugging interface.

They are phasing out the jtagice box and shifting to a ice300 with similar
capability and the 1-wire debug interface.

Hope that clears things up a bit.
