dm vs pm

I am porting code from an old board using a 21060 with limited memory, to the 21469 EZ board (for now).  Inorder for the previous program to fit in the memory of the 21060 much of the variables were split between dm and pm.    Since I no longer have memory issues, I have removed most of the dm/pm and section definitions.

 

Some of the assembly spisificly calls dm(dmVar1),

 

My limited testing seems to indicate that pm(dmVar1) works fine too.

 

I know the DSP can access pm and dm in paralell, other then this is there anything I am missing, or gotchas that will come up?

 

Thanks

Nick
