Flash Core Array Selection for Unlock Operation
The LSB and MSB Flash Cores in a OneNAND DDP configuration power-up in a locked state and must be unlocked before opera-
tion. Set DFS and DBS = "0" to select the LSB Chip or "1" to select the MSB chip, then issue Unlock Command Sequence: Start block
address+End block address+Unlock block command (0023h).
Note that the LSB and MSB chips must each be unlocked. The default state for Device BufferRAM Select (DBS) and Device Flash
Core Select (DFS) = "0", which selects the LSB chip. For more information on lock operations.

BufferRAM Selection for Read/Write Operation
The LSB and MSB chip BufferRAMs operate independently. Select the desired LSB or MSB chip and then execute a BufferRAM
Read/Write operation. The default state for Device BufferRAM Select (DBS) and Device Flash Core Select (DFS) = "0", which selects
the LSB chip.
