at89c52 Code Banking

Hi,

Please can anyone help me?
I'm using at89c52. Can you guide me how to do the configuration keil code banking?

I have do some testing. I create x1 common x23 bank's. After i compiled, it just generate the bank hex file. May i know how to generate the common.c hex file? Is it necessary to have common.hex to burn into MCU registers? The x bank.hex will be in to EEE2PROM.

Please can you check for me is it the circuit correct not?

Thank you very much.....
