Writing the ECC can not be done using the NFC so it needs to be done “manually”.
Note that instead of using the interrupt one can poll the NFCBUSY Flag.
For more information on the NFC Control Register, see
Command”.
A page in NAND Flash and SmartMedia memories contains an area for main data and an addi-
tional area used for redundancy (ECC). The page is organized in 8-bit or 16-bit words. The page
size corresponds to the number of words in the main area plus the number of words in the extra
area used for redundancy.
Over time, some memory locations may fail to program or erase properly. In order to ensure that
data is stored properly over the life of the NAND Flash device, NAND Flash providers recom-
