Can anybody say the concept of Extended Memory Space? I am not sure what it exactly means. I saw a microcontroller P89C669 which has 96KB in built Falsh and 2KB RAM. But they have mentioned that extended memory space can go upto 8MB.
How to implement the extended memory space function? Is this purely thru software or by hardware expansion?
