Don't trust a datasheet blindly. Always apply common sense and
a bit of caution. Especially when it comes to Atmel.

In the past 2 years, i've discovered 3 silicon bugs in Atmel chips
and two "bugs" in their documentation. Reporting the silicon bugs
resulted in being completely ignored and the documentation bugs
were answered with (literally) "it's a silicon thing", completely
disregarding the fact that following the documentation will cause
hard to trace bugs in the software (that's how i discovered them
in the first place).
