Is it possible to place some critical variables, as near memory type, in the on-chip 1K memory, yet other non-critical variables, still declared as near memory type, in the external memory? In other words, how do you explicitly place two variables, both declared as near, into two seperate memory spaces - on-chip 1k and external memory?
Sorry I forgot to mention this is 251 part. Access to XDATA is much slower than access to "near" memory. It is accessed indirectly through the data pointer(DPTR) while access to near is using direct addressing. I could use SEGMENTS directive to place particular segment in the memory space I wanted, but with quite few files in the project, this way is very painful.
