Using XRAM and EEPROM in CC01

James Finney

Hi, I'm hoping somebody can answer the following without me having to figure it out the hard way :) -

Im using the Atmel T89C51CC01 for a project. Configuration data is held in the EEPROM and retrieved from the EEPROM and stored in XRAM on startup.

At the moment the two don't need to over lap because im only using under 1K, but now i need to store over 1K.

The question is: Since the XRAM and EEPROM address spaces are shared, i presume i cannot read from the upper 1K of EEPROM and store it into an XRAM variable at the same address (or near by)?
