Hi Anitha, You may, or may not, be aware of this, but this group has had a policy (unwritten) that the header files will match the XML device file that is shipped with AVR Studio.
So when fixing a definition value, be sure to check the corresponding XML device file in AVR Studio to make sure that they match.
