Hello, Quick check shows that for xmega (all?) have power_aes_enable() and power_aes_disable() methods commented in power.h
The changes were made when xmega was newly supported in avr-libc in revision 1657. Diff: http://svn.savannah.nongnu.org/viewvc/trunk/avr-libc/include/avr/power.h?root=avr-libc&r1=1655&r2=1657 I have referred to xmega A reference manual. It seemed to have power reduction registers set and AES bits defined. Any particular reason why these methods have been disabled? Thanks Anitha _______________________________________________ AVR-libc-dev mailing list AVR-libc-dev@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-libc-dev
