•  Supports STK500 FW 2.XX 
1 Introduction 
This document describes the 2.0 version of the communication protocol between 
the Atmel STK500 and the PC controlling the STK500. The firmware is distributed 
with AVR Studio 4.11 build 401 or later.  
The definition of all commands, responses, parameters and other defined values 
can be found in the file “command.h”. This file can be downloaded from the Atmel 
web site. 
Most device specific values can be found in the xml files for each part. The xml files 
are distributed with AvrStudio 4.11 or later. Download the latest AVR Studio 4.x 
from the Atmel web site, 
is described in section 6. For values not present in the XML file, please refer to the 
device datasheet. 
This document mainly refers to STK500, but mostly everything also applies to the 
AVRISP. In the few cases where the behavior is different between STK500 and 
AVRISP, it will be noted.
