using the NDFC, power consumption can be reduced by setting this bit to “0”.

(a) <SYSCKE>
(b) <ECCS>
(c) <BUSW>
This bit is set to “0” for using Hamming codes and to “1” for using Reed-Solomon codes. It
is also necessary to set this bit for clearing ECC.
0100~1111
The <ECCS> bit is used to select whether to use Hamming codes or Reed-Solomon codes.
The <SYSCKE> bit is used for both Hamming and Reed-Solomon codes.
When using the NDFC, this bit must be set to “1” to enable the system clock. When not
The <BUSW> bit is used for both Hamming and Reed-Solomon codes.
This bit specifies the bus width of the NAND Flash to be accessed (“0” = 8 bits, “1” = 16
