A debugger, like the AVR Studio, may however use one or more of these resources for its inter-
nal purpose, leaving less flexibility to the end-user.
A list of the On-chip Debug specific JTAG instructions is given in “On-chip Debug Specific JTAG
The JTAGEN Fuse must be programmed to enable the JTAG Test Access Port. In addition, the
OCDEN Fuse must be programmed and no Lock bits must be set for the On-chip Debug system
to work. As a security feature, the On-chip Debug system is disabled when any Lock bits are set.
Otherwise, the On-chip Debug system would have provided a back-door into a secured device.
The AVR JTAG ICE from Atmel is a powerful development tool for On-chip Debugging of all
AVR 8-bit RISC Microcontrollers with IEEE 1149.1 compliant JTAG interface. The JTAG ICE
and the AVR Studio user interface give the user complete control of the internal resources of the
microcontroller, helping to reduce development time by making debugging easier. The JTAG
ICE performs real-time emulation of the microcontroller while it is running in a target system.
Please refer to the Support Tools section on the AVR pages on www.atmel.com for a full
description of the AVR JTEG ICE. AVR Studio can be downloaded free from Software section
on the same web site.
All necessary execution commands are available in AVR Studio, both on source level and on
disassembly level. The user can execute the program, single step through the code either by
tracing into or stepping over functions, step out of functions, place the cursor on a statement and
execute until the statement is reached, stop the execution, and reset the execution target. In
addition, the user can have an unlimited number of code breakpoints (using the BREAK instruc-
tion) and up to two data memory breakpoints, alternatively combined as a mask (range) Break
Point.
