DEBUG AVR APPLICATIONS USING
JTAG OR DEBUGWIRE INTERFACE
The AVR® JTAGICE mklI 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 or debugWIRE Interface. DebugWIRE enables on chip debug of AVR
microcontrollers in small pin count packages, using only a single wire for the
debug interface. The JTAGICE
mkII 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 JTAGICE
mkII performs Real Time emulation
of the microcontroller while it is
running in a target system. The
JTAGICE mkII provides emulation
capability at a fraction of the cost of
traditional emulators.

AVR ON-CHIP DEBUG SYSTEM
The JTAGICE mkII allows access to all the powerful features of the AVR microcontroller. All AVR resources can be monitored: Flash memory, EEPROM memory,
SRAM memory, Register File, Program Counter, Fuse and Lock Bits, and all I/O
modules. The JTAGICE mkII also offers extensive On-chip Debug support for break
conditions, including break on change of Program memory flow, Program memory
Break Points on single address or address range, and Data memory Break Points
on single address or address range.
The debugWIRE uses the Reset line for
electrical connection; hence the system
designer does not have to sacrifice I/O
capabilities to take full advantage of
the On-Chip-Debug system.
