HW_BCH_MODE

0
Reserved, always set these bits to zero.
This value indicates the maximum number of zero bits on a flash page for it to be considered erased. For
SLC NAND devices, this value should be programmed to 0 (meaning that the entire page should consist of
bytes of 0xFF. For MLC NAND devices, bit errors may occur on reads (even on blank pages), so this threshold
can be used to tune the erased page checking algorithm.
27
0
Reserved, always set these bits to zero.
1 = All data bits of this transaction are ONE.
1 = At least one correctable error encountered during last processing cycle.
1 = Uncorrectable error encountered during last processing cycle.
Reserved, always set these bits to zero.
