I'm working with a 32K microcontroller using external code banking. The external bank area is in address 0x8000- 0xFFFF and I have 16 banks of 32K. If I configure a function in bank 0 I see that its code is in address 0x8000, but if I configure this function in bank 1 I see that code is in 0x18000. I think if the size of the banks is 32K, if I choose Bank 1 for this function I should see the code of this fcn. in address 0x10000.
I heard lot of theories for code banking but yet dont know how to practically implement it using 8051 hardware & keil software? My code banking concept is not clear, can anyone pls explain me in very simple & prctical terms aided with clear hardware schematic & software code examples? I want to interface 512KB of non-volatile Data RAM / EEPROM / Flash to Philips P89C668 (8051 core). Does anyone know good links to the same? What extra coding logic is required with Keil C code? -Meghal.
Meghal Vasa, As this is not specifically related to the foregoing discussion, you should start a new Thread for your topic. You are actually asking about Data banking, not code banking - they are somewhat difrerent!
