    not much internal data in cpu so less to copying and faster. yes?..

    And that is the reason why an ISR should not need to copy any data, and know about the size of data segments. The time the ISR takes to do it's work should not be affected by the amount of memory the main application needs. If you can't guarantee a worst-case execution time for an ISR, you whould have to perform a full requalification of your application for every minimal change you do anywhere in the application.
