Function of 8K on-chip RAM -  EZ-USB FX CY7C646xx

Version 1
    Question: When I use the expanded memory space of the EZ-USB FX CY7C646xx for code and xdata, what's the function of the 8K on-chip RAM?



    The on-chip 8K RAM of EZ-USB FX CY7C646xx will still be available for use, but any code or xdata in the first 8K block will not generate RD# and WR# strobes to the external memory chip.
