I'm planning to use the FSMC to memory-map registers of a FPGA. To save pins I would like to use multiplexing between data and address lines. Now, I need only a 8-bit data bus width but would like to address more than 2^8 bytes. This essentially means that the first 8 address/data lines are multiplexed while the upper address lines are not. Is that possible? How would I configure the FSMC to use 8-bit data width but 10-bit addressing?
