This is the area where the AVR is big-endian (as Georg-Johann already
mentioned).  To add to the confusion, the saved address could have
bits set that are not part of the PC on that device, making it really
hard to spot when looking at a stack dump.  This is e.g. known for the
ATmega16.

Keep in mind that the return address is stored on the stack as a word
address, while the GNU tools use byte addressing for everything.
