Thank you for sharing the link. It is really informative.

So by changing the memory allocated to IDATA and PDATA segments I can change how my RAM is used, right?
Also, why is heap memory not allocated to XDATA?

I suggest you not to change IDATA and PDATA unless you know exactly what you're doing.
