    [Remark] The boldface files are the key files for NAND flash driver porting. When users use different NAND flash devices, they still use the same LPC3180 on-chip NAND flash controller that has the same code implementation. We can port the NAND flash driver with modifying only the device dependent codes.

    We should be clear that users may connect different kinds of NAND flash devices, but they use the same NAND flash controller – LPC3180 on-chip NAND flash controller. It’s the NAND flash controller that gives the sequential logic control on the NAND flash device.
