ECC Information[15:0]
2.8.27 ECC Result of 1
This Read register shows the Error Correction result for the 1st selected sector of the main area data. ECCposWord0 is the error
position address in the Main Area data of 256 words. ECCposIO0 is the error position address which selects 1 of 16 DQs.
ECCposWord0 and ECCposIO0 are also updated at boot loading.
FF01h, default = 0000h
2.8.28 ECC Result of 1
This Read register shows the Error Correction result for the 1st selected sector of the spare area data. ECClogSector0 is the error
position address for 1.5 words of 2nd and 3rd words in the spare area. ECCposIO0 is the error position address which selects 1 of 16
DQs. ECClogSector0 and ECCposIO0 are also updated at boot loading.
FF02h, default = 0000h
