I've done several designs using standard AVRs but it's time to do my first with the ATxmega128A1.
Regarding crystal selection, what is suitable crystasl load capacitance (CL) for a 16 MHz together with the ATxmega128A1? Standard values for crystal CL is 8pF, 9pF and 10pF.
In previous designs I've also used external caps to add extra CL, 22 pF is standard value there.
So, what should I choose as crystal CL for a ATxmega128A1?
