OTP Block Program Operation Flow Chart
NOTE :
1) FBA(NAND Flash Block Address) could be omitted or any address.
2) ‘Write 0 to interrupt register’ step may be ignored when using INT auto mode. Refer to chapter 2.8.18.1
3) Data input could be done anywhere between "Start" and "Write Program Command".
4) FBA must be 0000.
5) FSA must be 00 within program operation.
6) BSA must be 1000 and BSC must be 000.
