it's off on old PR.....what it means is .....they do not shadow files.
It's a bit stream directly off the flash....the faster the ability of the memories read....the faster the rate transfer. Unplug the memory and the sequence stops.
MicroOS is only limited by the speed of the memory to manage in the way they do....without shadowing, status quo paging....or directive structure maintenance.
It's a path to device periphery without the hassles.
