I'm not sure of the TigerSharc specifically, but the Sharc family in general
shouldn't have any issues in setting up the WAIT register (which sets up the
wait states).
Why do you want to setup the wait states before accessing memory and revert
to another value? Wait states don't affect internal accesses, so you should
just set it up at the initialization phase in your code and not mess with
it.
I'm sure others with TigerSharc experience will chip in with more details...

Hi, I hope someone can help me with my problem. In my DSP program I
want to change the wait states during the execution of my program, but
I can't get the DSP to change the wait states. It appears the wait
state settings are locked in at reset. Does anyone know if it is
possible to change the wait states during execution, for example,
change the wait states to read external memory and then change them
back after the read?
thanks,
