gcc-armxxx places "volatile" data outside the cache... so it must be a compiler dependent feature. Always best to examine the resulting assembly to make sure your assumptions are correct :)

This varies by | CPU | and there is nothing in the language to help you with this. | _______________________________________________ AVR-GCC-list mailing list AVR-GCC-list@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-gcc-list
