 Debug opcodes for AVR JTAG interface are Atmel private!!!That's why AVaRice 
works only with AVR JTAG ICE available from Atmel. The controller in there 
tranlates AVaRIce or AvrStudio instructions into Atmel private debug JTAG 
opcodes.

 Sorry, up to now, nobody has published the definitions of Atmel private JTAG 
debug opcodes.
