The following electronic documents from Atmel ? are related to the use of the AVR ?
microcontrollers, and of the debugging tools. All documents can be found on the Atmel
Products CD-ROM enclosed in the ICE50 kit. For more information and document
updates, please visit our web site: www.atmel.com.
AVR Studio ? user's guide.
Describes in detail how to use the AVR Studio debugging environment.
Describes in detail how to use the AVR Assembler.
Data sheets for the different AVR devices.
Errata sheets for the different AVR devices.
Application notes describing different application examples for the AVR
microcontrollers.
Describes in detail how to use the AVR Studio debugging environment.
Note:
AVR Studio 4.0 or later is required for ICE50 support. AVR Studio 3.x versions
will not work with ICE50!
There has been several releases of the ICE50 firmware.
First released version.
Errors in trace module fixed.
Version table readout in main module fixed.
All parts with ADC: ADC bit 3 and 4 where interchanged. This is now fixed on all parts
with ADC.
Trace of Program Counter is now correct in single step.
Brown-out Detection (BOD): Selection of Brown-out Voltage is now enabled for all
parts.
Mega8: Reset Disable Fuse added to ICE50 options.
There are some known issues in the ICE50 that users needs to be aware of.
User break in sleep mode is not supported. Use an interrupt to wake up the part or a
reset to Reset the emulator.
User break in sleep mode is not supported. Workaround: A Reset will break and
reset the emulator.
The ADC may latch-up if the target is powered before the ICE. Also make sure that
no residual voltage is present on the ADC input pins if the ICE is not powered.
User break in sleep mode is not supported. Use an interrupt to wake up the part or a
reset to reset the emulator.
