Hello Heejeong Ryu, I'll start by assuming you are talking about an mcs51 target.
I'm not sure how XRAM is related to your problem, as xdata is usually a separate memory space from code. But maybe you have a Von-Neumann-ized design. If you want some code in a different segment from the rest, you can use --codeseg or #pragma codeseg to place it in anything other than CSEG. Then when linking you can place this segment at some fixed address. You can do something similar for constant data. For more details look in the manual or ask more detailed questions here.
