Note 1) FBA(NAND Flash Block Address) could be omitted or any address.
OTP Load(OTP Access+Load NAND)
OTP area is separated from NAND Flash Array, so it is accessed by OTP Access command instead of FBA. The content of OTP
could be loaded with the same sequence as normal load operation after being accessed by the command. If user wants to exit from
OTP access mode, Cold, Warm, Hot or NAND Flash Core Reset operation should be done.
* DBS, DFS is for DDP
