Hi, I'm trying to add support for the ATXmega(128/64)B(1/3) in the config file, however, I'm having trouble locating the required values in the datasheet. In particular, I don't know how to find the offsets for signature, fuse and lock bytes.
Looking at the values for the ATxmega256A3 in the config file, I find some very large values for these offsets, but looking at the ATxmega256A3 datasheets I could not figure out where they came from. For example, in http://www.atmel.com/Images/doc8077.pdf table 4.22 on page 46 lists the address of fusebyte0 as +0x00 on page 30. But relative to what? So where did 0x8f0020 listed in the config file come from? Also, table 4.23 lists 63 registers for production signature row, yet in the config file it says that prodsig has size of 0x200 (512). Where do I get the proper values from? Finally, I'm also wondering whether there's stuff missing from the configuration for the XMegas. Looking at the ATmega1284P there's so much more configuration items that are not present at the XMega, why is that?
