#119317 - flat or banked memory ? Responding to: ???'s previous message |
You need to select the right addressing scheme on the compiler, which fits the hardware.
E.g. DS80C390, P89C669 can address 4MB code/data directly, if you select the appropriate compiler options. Otherwise you must give the compiler a piece of assembler code to switch between memory banks. On code memory banking there must also always be a common segment, which was identical in all banks, for the bank switching code and for interrupts. Peter |
