89C51 with internal XRAM and EEPROM

I am using an 89C51 variant with both intenal XRAM and EEPROM and as such their address space overlaps from 0x0000 to 0x03FF so I have variables declared as follows:- #define size 0x20 /* variables...

Does Keil simulator fix pdata on on-chip XRAM page 0 if on-chip XRAM MCU present?

I build a C51 program and want to show someone else how the pdata variable is stores in C51. The result seemed there exit some problem. I found if I select non on-chip XRAM such as Philips P89C51, the...
