NOTES
1.
Due to the increasingly short lifetimes of system components, the I/O devices used on the PPC11A are
not guaranteed to remain fixed in the future.
2.
Hardware should be accessed only through mechanisms provided by the Operating System’s Board
Support Package, and not directly by application software.
3.
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.
4.
Abaco-supported Operating Systems guarantee compatibility at the application level through
hardware independent mechanisms.
