OTP Lock Operation Flow Chart
Start
Write ’FPA, FSA’ of Flash
Add: F107h DQ=0000h
Write ’BSA, BSC’ of DataRAM
Add: F200h DQ=0001h
Write Data into DataRAM
2)
Add: 8th Word
in spare0/sector0/page0
Write Program command
DQ=0080h or 001Ah
Wait for INT register
low to high transition
Add: F241h DQ[15]=INT
Add: F220h
Write 0 to interrupt register
Add: F241h DQ=0000h
Automatically
updated
DQ=XXXCh
Update Controller
Status Register
Add: F240h
DQ[6]=1(OTP
L
)
OTP lock completed
Write ’FBA’ of Flash
Add: F100h DQ=FBA
3)
Write ’OTP Access’ Command
Add: F220h DQ=0065h
Wait for INT register
low to high transition
Add: F241h DQ[15]=INT
Write 0 to interrupt register
Add: F241h DQ=0000h
Do Cold reset
Write ’DFS’, ’FBA’ of Flash
1)
Add: F100h DQ=DFS, FBA
Select DataRAM for DDP
Add: F101h DQ=DBS*
* DBS, DFS is for DDP
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.
Note 1) FBA(NAND Flash Block Address) could be omitted or any address.
