Technically, our policy is to match the XML part description file in AVR 
Studio. So you need to see what the XML file says and compare that against the 
datasheet. The problem could be in the datasheet. To verify that it truly is a 
bug, make sure you have the latest version of the datasheet (from the Atmel web 
site), and make sure you have the latest AVR Studio version (for the latest XML 
file). Then you need to check the avr-libc project to see if that the problem 
has already been fixed (but just not released yet). To do this you can view the 
avr-libc CVS repository via the web here: 
<http://cvs.savannah.gnu.org/viewvc/?root=avr-libc>. If it's truly a bug, then 
please file a bug report at the avr-libc project here: 
<https://savannah.nongnu.org/task/?group=avr-libc&func=additem>. Emails sent to 
the list get lost very quickly. Submitting a bug report is the best way to 
ensure that the problem will get fixed.
