JC, That is correct on the external xtal. DFLL adjust / turns the internal oscillators. There is errata on this from Atmel and it is noted in the BASCOM help file under Xmega. The problem is that the...

The last Datasheet of 128A1 gives the internal 32MHz an accuracy of +/- 1.5%, the internal 32.768kHz +/- 0.5% - all at 85°C (185°F)!! Over the Temp-Range you have another 2% for the internal 32.768kHz...
