Reading Duty Cycle with an XMEGA384C3
Change: OSC.CTRL = OSC_RC32MEN_bm; // enable 32MHz oscillatorTo: OSC.CTRL |= OSC_RC32MEN_bm; // enable 32MHz oscillatorAnd test again.

Xmega ADC internal temperature sensor problems
This is an old thread. But according to my posts I think XMEGA internal temperature sensor with +-15C accuracy is only appropriate for 85C over temperature detection and...

what happen when a event syeteam channel trigger a pin?
From Manual:   An event normally lasts for one peripheral clock cycle, but some event sources, such as a low level on an I/O pin, will generate events continuously. Details...

xmega interrupt vectors...
TCxy means Timer/Counter of type y on PORTx. So TCE0_INT_base is the interrupt base for a type 0 Timer/Counter which waveform pins are on PORTE.

A note on XMEGA frequency generation mode
More experiments show that channel A toggles on TOP (moving from top to bottom). But the case is different for other channels and the related pins toggle on BOTTOM (moving from...

Switching from Mega to Xmega?
It is also important: AVcc - 0.6 is the maximum limit for XMEGA ADC reference, which makes some problems (for example, when connecting 4 wire resistive touch panels).
