7.27 ECC Status Register(R): FF00h, default=0000h
ERm
(ECC Error for Main area data) &
ERs
(ECC Error for Spare area data)
ERm0/1 is for first/second
selected sector in main of BufferRAM,
ERs0/1 is for first/second
selected sector in spare of BufferRAM.
ERm and ERs show the number of error bits in a sector as a result of ECC check at the load operation.

NOTE
:
1. ECCposWord: ECC error position address that selects on one of Main area data(256words)
2. ECCposIO: ECC error position address which selects one of sixteen DQs (DQ 0~DQ 15).
3. ECClogSector: ECC error position address that selects one of the 2nd word and LSB of the 3rd word of spare area. Refer to the below table.
ECClogSector Information [5:4]
4. ECCposWord, ECCposIO and ECClogSector are updated in boot loading operation, too.
