How to access EDATA memory on P89c669

Hi,

I am using the P89c669 micro controller and I want to use the EDATA memory of the MCU as the general purpose data memory. I have included the START_MX.A51 file in the my code. So please tell me what changes I need to do in this file to access this extra data memory.

thank You.

a general answer:

in (a renamed local version of) startup.a51 you need to set the appropiate SFR to match your memory configuration
