NOTES
Due to the increasingly short lifetimes of system components, the I/O devices used on the SBC347A are
not guaranteed to remain fixed in the future.
Hardware should be accessed only through mechanisms provided by the Operating System's Board
Support Package, and not directly by application software.
If a standard operating system is not being used, then it is recommended that applications are written in
such a way as to minimize direct access to hardware resources, bearing in mind that changes may be
necessary to support future iterations of the hardware.
Abaco-supported Operating Systems guarantee compatibility at the application level through hardware
independent mechanisms.
