    Typically program is allocated to page 0 and data to page 1.  Since C2000 has unified memory (same physical memory is available in both program and data space) it doesn't really matter. 

    Note that there is one exception to this that I can think of.  Some flash programmers - such as SDFlash - will only pickup sections mapped to page 0 for flash programming.  In this case you need to have any constants or switch sections assigned to page 0 or the programmer won't pick it up.  The code composer studio flash plug-in does not have this limitiation.
