I have to expand 64K ROM by interfacing 32k external ROM's. Let me know how to do the mapping and bank switching and the procedure.
Thanks in Advance Rajat Kumar
You've read the sections in the Manuals on how to do this - right?
Yeah I do have an overview about code banking but want to go through a sample code to understand how to switch and how to store separate functions in separate banks.
I got a manual for code banking inside 128K ROM at www.atmel.in/.../doc7639.pdf but i need same sort of thing for using external ROM's of 32K each with 64K internal ROM.
I am using an external ROM of 256 K what will be the Keil target destination setting for 4 banks with 1) each having 32kcommon and bank code 2) bank 0 for common and bank 1 ,2 ,3 for bank code
