14.4.10.2.1. Main Area Transfer Mode

In main area transfer mode, when ECC is enabled, the NAND flash controller inserts ECC check bits in the data stream on writes and strips ECC check bits on reads. Software does not need to manage the ECC sectors when writing a page. ECC checking is performed by the flash controller, so software simply transfers the data.

If ECC is turned off, the NAND flash controller does not read or write ECC check bits.
