Пипец, до чего дошли...avreal писал(а):Всё, забудьте. R0..R31 в Xmega не адресуются как память, как это было у остальных AVR.
А GPIO -- это другое. Таких регистров по одному-два-три и у свежих "обычных" AVR-ок есть, доступны для in/out и, что приятно, для размещения глобальных битовых флагов под sbi/cbi/sbis/sbic, так как с байтами в ОЗУ AVR8 такого не умеют.
