Choosing between ITCM and DTCM on IMXRT

I believe that ITCM can be used for R/W variables as well as code. Similarly DTCM be used for code as well as R/W variables. I assume that code, (and const data?), should be placed in ITCM and R/W variables should be placed in DTCM. Is there a simple guide that illustrates why this is so? I'd be interested to know why R/W variables shouldn't be put in ITCM or why code shouldn't be put in DTCM.
