14.4.10.2.3. Main+Spare Area Transfer Mode

In main+spare area transfer mode, the NAND flash controller expects software to format a page as shown in following figure. When ECC is enabled during a write operation, the flash controller‑generated ECC check bits replace the ECC check bit data provided by software. During read operations, the flash controller forwards the ECC check bits from the device to the host. If ECC is disabled, page data received from the software is written to the device, and read data received from the device is forwarded to the host.
