"you can change such XDATA variables into the internal RAM and no longer an external SRAM was needed."

I'm using xdata for eeprom and using the _at_ directive as told by erik 3 months ago.
I use eeprom variables for timing parameters.
If i copy them into internal ram i might have 2 problems
1. cant afford to make my internal ram over 80% otherwise i will get out of control if my stack exeeds the available memory.

2. I will have a problem on how and when to update the internal memory from eeprom variables.
Simplisty is my 'moto' in programming and just using the eeprom variable in xdata with the _at_ directive suits me fine.
