NAND flash controller enable/disable
0 = Disable NAND Flash Controller
1 = Enable NAND Flash Controller
After auto-boot, this bit is cleared to 0 automatically.
For the access to the NAND flash memory, this bit must
be set.
Reserved
Initialize ECC decoder/encoder
0 : Not initialize ECC
(S3C2410A supports only 512-Byte ECC checking, so it is
required to set ECC initialization per 512 Bytes.)
NAND flash memory nFCE control
0 : NAND flash nFCE = L (active)
1 : NAND flash nFCE = H (inactive)
(After auto-boot, nFCE will be inactive.)
CLE & ALE duration setting value (0~7)
Duration = HCLK * (TACLS + 1)
Reserved
TWRPH0 duration setting value (0~7)
Duration = HCLK * (TWRPH0 + 1)
Reserved
TWRPH1 duration setting value (0~7)
Duration = HCLK * (TWRPH1 + 1)
