the NAND Flash are performed through the ND0FDTR register. The actual write operation
completes not when the ND0FDTR register is written to but when the data is written to the
external NAND Flash. Likewise, the actual read operation completes not when the
ND0FDTR register is read but when the data is read from the external NAND Flash.
