Is there an issue with this code when run on a XMega that requires ISR's to end with RETI? Need a XMega and non-XMega version of this function? Doesn't sound good. Normal prolog/epilog deal with that I believe but this is intended to be 'naked'. How do you get automatic RET vs RETI? _______________________________________________ AVR-libc-dev mailing list AVR-libc-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/avr-libc-dev
