Introduction
Thank you for buying our JTAGcable II emulator. We hope that the great power it
offers will allow you to appreciate fully the virtues of debugging and programming in
the system provided by Atmel microcontrollers.
JTAGcable II constitutes a tool for programming, real-time emulation in the target
circuit and debugging of processors of the AVR family of Atmel microprocessors
equipped with a JTAG interface. It is fully compatible with the original AVR JTAG ICE
from Atmel. It forms, together with AVRStudio software, an up-to-date and
professional environment for the start-up of programs written both in low-level
(Assembler) and high-level (C) languages.
JTAG is a four-wire interface permitting takeover of control of the processor’s core
and its internal peripherals. The possibilities offered by this interface are, among
others, stepped operation, operation at full speed, circuit and software traps,
monitoring and modification of register contents and data memories. Moreover,
functions offered by ISP programmers are available, such as: programming and read-
out of Flash memories, EEPROM, fuse-and-lock bits.
JTAGcable II can co-operate with microcontrollers supplied with voltages from 1.8 to
6 V. Such a broad range of supply voltages was achieved through buffering of signals
on the JTAG line, additionally enhancing the immunity of the circuit to interference.
The set is provided with AVRStudio software from Atmel, working in the Windows
system.
A detailed operating instruction of the emulator and of the AVRStudio program can be
found at the website of Atmel: http://www.atmel.com
Let us wish you nothing but success and a lot of satisfaction in
designing and putting new microprocessor devices to work.
