14.4.8.3. MAP10 Commands

MAP10 commands provide an interface to the control plane of the NAND flash controller. MAP10 commands control special functions of the flash device, such as erase, lock, unlock, copy back, and page spare area access. Data passed in this command pathway targets the NAND flash controller rather than the flash device. Unlike other command types, the data (input or output) related to these transactions does not affect the contents of the flash device. Rather, this data specifies and performs the exact commands of the flash controller. Only the lower 16 bits of the Data register contain the relevant information.
