ECCType [24:23] This bit indicates what kind of ECC should be used.
00 = 1-bit ECC
10 = 4-bit ECC
01 = 8-bit ECC
Note:
Don’t confuse the value of 4-bit ECC and 8-bit ECC.

PageSize
[3]
This bit indicates the page size of NAND Flash Memory
When PageSize_Ext is 1, the value of PageSize means
following:
0 = 512 Bytes/page,
1 = 2048 Bytes/page
When PageSize_Ext is 0, the value of PageSize means
following:
0 = 2048 Bytes/page, 1 = 4096 Bytes/page
H/W Set
(CfgAdvFlash)
PageSize_Ext
[2]
This bit indicated what kind of NAND Flash memory is used.
0 = Large Size NAND Flash
1 = Small Size NAND Flash
This bit is determined by OM[2] pin status on reset and wake-
up time from sleep mode.
This bit can be changed by software later.
