35.4.2.1 MLC/SLC Read Operation with Spare Decoding

When the spare area is protected, the spare area contains valid data. As the redundancy may be included in the middle of the information stream, the user programs the start address and the end address of the ECC area. The controller will automatically skip the ECC area. This mode is entered by writing a ‘1’ to PMECC_CTRL.DATA. When the page has been fully retrieved from NAND, the ECC area is read using the user mode by writing a ‘1’ to PMECC_CTRL.USER.
