2.8.25 NAND Flash Write Protection Status Register F24Eh (R)
This Read register shows the Write Protection Status of the NAND Flash memory array.
To read the write protection status, FBA has to be set before reading the register
.
F24Eh, default = 0002h

2.8.26 ECC Status Register FF00h (R)
This Read register shows the Error Correction Status. The OneNAND can detect 1- or 2-bit errors and correct 1-bit errors. 3-bit or
more error detection and correction is not supported.
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 oper-
ation.
