II. Additional 512 bit secured OTP for unique identier: to provide 512 bit one-time program area for setting
device unique serial number - Which may be set by factory or system customer. Please refer to "Table 3. 512 bit
Secured OTP Denition".
- Security register bit 0 indicates whether the chip is locked by factory or not.
- To program the 512 bit secured OTP by entering 512 bit secured OTP mode (with ENSO command), and going
through normal program procedure, and then exiting 512 bit secured OTP mode by writing EXSO command.
- Customer may lock-down the customer lockable secured OTP by writing WRSCUR(write security register)
command to set customer lock-down bit1 as "1". Please refer to "Table 7. Security Register Denition" and "Ta-
ble 3. 512 bit Secured OTP Denition" for address range denition.
- Note: Once lock-down whatever by factory or customer, it cannot be changed any more. While in 512 bit se-
cured OTP mode, array access is not allowed.
