It will work anyway, only not as effective. Memory-mapped IO (MMIO) is the only method where access to the entire set of IO registers on the AVR can be guaranteed for all devices. If you turn on optimization, the optimizer will recognize that situation, and turn that into an "out 0x0c, r24" instruction. -- cheers, J"org .-.-. --... ...-- -.. .
