THERE ARE NO SPECIAL SFR BITS NEEDED TO ACCESS THE INTERNAL RAM FROM 0X80 THROUGH 0XFF. IF YOU ARE WORKING IN KEIL C JUST DECLARE ALL YOUR VARIABLES WITHOUT ANY SPECIFIC TYPING AND THE COMPILER AND LINKER SHOULD PLACE THEM IN THE AVAILABLE RAM AND SETUP THE NECESSARY ADDRESS METHODS TO ACCESS THEM. YOU CAN OF COURSE USE THE DATA AND PDATA ATTRIBUTES TOO IF YOU WANT TO MANAGE THINGS BY YOURSELF. THE STACK NORMALLY GETS LOCATED AT THE END OF THE LINKED DATA+PDATA VARIABLE LIST.
