If the physical memory device connected on one chip select is smaller than 64 Mbytes, it wraps
around and appears to be repeated within this space. The SMC correctly handles any valid
access to the memory device within the page (see
A[25:0] is only significant for 8-bit memory, A[25:1] is used for 16-bit memory, A[25:2] is used for
32-bit memory.
A data bus width of 8, 16 or 32 bits can be selected for each chip select. This option is controlled
by the field DBW in MODE (Mode Register) for the corresponding chip select.

as a single 32-bit memory.
Each chip select with a 16-bit or 32-bit data bus can operate with one of two different types of
write access: byte write or byte select access. This is controlled by the BAT field of the MODE
register for the corresponding chip select.
