II. Additional 512-bit secured OTP for unique identifier: 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 definition.
- 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 go-
ing 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 of "security register definition" for security
register bit definition and table of "512-bit secured OTP definition" for address range definition.
- Note: Once lock-down whatever by factory or customer, it cannot be changed any more. While in 512-bit se-
