Hello,

I am intended to use ATXMEGA32 MCU with both hi freq XTAL and 32kHz external crystal for RTC. Since XTAL and TOSC are at the same pins I want to use alternate option for TOSC. In ATXMEGA AU MANUAL at page 60 you can read this: Note: 1. TOSC pins can optionally be moved to PE2/PE3.
The problem is I cannot find which register that control this. Does anyone has experience with this? How to use this pins for external 32kHz crystal?

Thanks!
 

Hi,

According "XMEGA AU MANUAL".
chapter: 4.16.3 FUSEBYTE2
Bit5: toscsel
0= alternate location, 1= XTAL location
