Features:

AVR-JTAG (complete analog of ATMEL’s

AVR JTAG ICE) is development tool for

programming,

debugging for AVR microcontrollers JTAG

interface (ATmega16, ATmega32, ATMega323,

ATmega162, ATmega169, ATmega128). AVR-

JTAG have: JTAG 10 pin connector (Atmel

layout), status LED, RS232 connector

AVR-JTAG 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. AVR-JTAG 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.

and

Programming:

To work with AVR-JTAG you need target board

with JTAG connector (for instance Olimex’s

AVR-M16 + AVR-P40B-P8535-8Mhz) and

AVRSTUDIO software ( you can download from

http://www.avrfreaks.net in Tools section).

JTAG interface:

The JTAG connector is 2x5 pin with 0,1" step

and Atmel’s compatible layout. The PIN.1 is

marked with square pad on bottom and arrow on

top. JTAG signals are: 1- TCK, 2- GND, 3-

TDO, 4- VREF, 5- TMS, 6- NSRST, 7- VCC, 8-

NTRST, 9- TDI, 10- GND.
