15.5.2.3.3. Configure for Spare Area Access

To access only the spare area of the flash device, use the MAP10 command to set up the NAND flash controller to read or write only the spare area on the device. After the flash controller is set up, use MAP01 read and write commands to access the spare area of the appropriate block and page addresses. To configure the NAND flash controller to access the spare area only, perform the following steps:
  1. Write to the command register, setting the CMD_MAP field to 2 and the BLK_ADDR field to the target block.
  2. Write 0x41 to the Data register.
