jtag ice 16

Yes,with JTAG you can do software debugging and programming of micro in both JTAG and in ISP mode.

In JTAG mode you can program FLASH and EEPROM and Fuse bits ,you can do this also in ISP mode of JTAG ICE.

Thats correct because ISP uses SPI interface for programming and JTAG uses Test Port signals as defined in JTAG specs. Thats why programming algorithm and signals used in both the cases are also different. Basically programming is achieved in two totally different ways.

In AVR studio in tools menu connect to JTAG ICE.

In the appeared windows you can select JTAG as interface and program micro with JTAG port (you should use JTAG connector in hardware)

I the appeared window you can select ISP as interface and program micro with ISP port(you should use ISP connector in hardware0

I have successfully built JTAG ICE clone and it is working for me. yes you can program AVRs with this JTAG adapter, but only those who have JTAG port in it.
