I am trying to use the power reduction structures in a program for a xmega256d3 chip.
Using AVRStudio 4.18 SP3, atmels toolchain 3.2.3 for windoze.

And I dont seem to be able use PR.PRGEN to set anything. or in fact anything to do with the PR structure.

Looking in iox256d3.h, it doesnt even define PR, which it does for other chips.

Am I missing something?

IAR an winavr have not any definition of power reduction registers for ATXMEGA256D3. But I cannot find anything about this in atmel documents.

The datasheet for the D3 contains the PR registers, and I can find on the atmel site IAR header file that contains the registers/structures defined.
