I'm not familiar with this specific device or programming it with this library.

The way that it's been added does make sense and looks good to me. I was able to verify flash size, signature, and page size with values in the datasheet.

I'm not familiar with this specific device or programming it with this library.

The way that it's been added does make sense and looks good to me. I was able to verify flash size, signature, and page size with values in the datasheet.

With AVRs, setting up the chip is a matter of referencing the actual hardware - eg where the clock originates from. Obviously this needs to be set up by each individual user. I've set the 644PA stencil up for external crystal 8MHz.
Then there's the lockbits. Those have been left as open as I could. Again, each individual user is responsible for closing relevant fuses herself.
