2.8.26 ECC Status Register 1 FF00h (R)
This Read register shows the Error Correction Status. The Flex-MuxOneNAND can correct up to 4-bit errors.
ECC can be performed on the NAND Flash main and spare memory areas. The ECC status register can also show the number of errors in a
sector as a result of an ECC check in during a load operation. ECC status bits are also updated during a boot loading operation.
