FLASH MEMORY

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.

FF00h, default = 0000h
