what to use (sem/spinlock/etc)....

[RANDAZZO]

I have a register on my hardware that I write to to increment a counter....
..all I want to do is make sure that only one "task" writes at a time, 
thus to not corrupt the value......

=EXAMPLE

Task A
- Write new Value to hardware
- Increment Hardware counter
- DONE

Task B
- Write new Value to hardware
- Increment Hardware counter
- DONE

..This will most likely not occur in a inthandler, but may....

...I have to make sure that Task A is "done" before "Task B" or any others
can do their writing....

...any opinion of what I should use....
