NOTE :

1)FBA(NAND Flash Block Address) could be omitted or any address.

2)Data input could be done anywhere between "Start" and "Write Program Command".

3)FBA should point the unlocked area address among NAND Flash Array address map.

4)‘Write 0 to interrupt register’ step may be ignored when using INT auto mode. Refer to chapter 2.8.18.1.
