The Atmel JTAG ICE target interface provides access to Atmel’s JTAG ICE Mk I. This target interface supports program loading and debugging and access to the fuse and lock bits. When debugging with the JTAG ICE you will have access to four hardware breakpoints, however one of these breakpoints will be needed for single stepping. Two of the hardware breakpoints may be used as data breakpoints.
