A debugger, like the AVR Studio, may however use one or more of these resources for
its internal purpose, leaving less flexibility to the end-user.
A list of the On-chip Debug specific JTAG instructions is given in “On-chip Debug Spe-
cific JTAG Instructions” on page 224.
The JTAGEN Fuse must be programmed to enable the JTAG Test Access Port. In addi-
tion, 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 inter-
nal 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 instruction) and up to two data memory break-
points, alternatively combined as a mask (range) Break Point.
The On-chip Debug support is considered being private JTAG instructions, and distrib-
uted within ATMEL and to selected third party vendors only. Instruction opcodes are
listed for reference.
