Tue 20 Jul 2010 08:08:44 PM UTC, comment #1: The ATmega324P.xml device file from AVR Studio has duplicate <SIGNATURE> tags with different data in them. This is Atmel bug #11908. When this bug is fixed, separate header files need to be generated for the ATmega324P and ATmega324A and included in avr-libc (currently they use a single iom324.h header file), and io.h modified accordingly. |

iom324pa.h has registers like SPCR0, SPSR0, SPDR0 and their bits, that have a different name in the datasheet.

Yes, really all three variants need to have updated header files. I'll make sure and do that after the Atmel bug is fixed.
The link to the bug was automatically put in by Savannah, and it thinks that it's a bug on this system, which it is not. This is an Atmel-internal bug number. Sorry for any confusion.
