14.4.10. ECC
The NAND flash controller supports 512‑ and 1024‑byte ECC sectors. The flash controller inserts ECC check bits for every 512 or 1024 bytes of data, depending on the selected sector size. After 512 or 1024 bytes, the flash controller writes the ECC check bit information to the device page.
ECC information is striped in between 512 or 1024 bytes of data across the page. The NAND flash controller reads ECC information in the same pattern and performs a calculation to check for the presence of errors.
