| I have GQ-4X Programmer add definition to devices.txt file info for MX25L12873FPI (Name="MX25L12873FPI",ID="C22018",Class="W25X10",Category="SERIAL_EPROM",MFG="Macronix",Vcc="3.6V",CodeSize="16777216",EepromSize="128",Platform="GQ-4X";).
Recognized well but I don't know if programmer has the ability to recognize the feature "Additional 4K-bit secured OTP" to MX25L12873FPI.
Any idea, please?
Some info from manual:
Additional 4K-bit secured OTP for unique identifier: to provide 4K-bit one-time program area for setting device unique serial number - Which may be set by factory or system customer.
- Security register bit 0 indicates whether the chip is locked by factory or not.
- To program the 4K-bit secured OTP by entering 4K-bit secured OTP mode (with Enter Security OTP command),
and going through normal program procedure, and then exiting 4K-bit secured OTP mode by writing Exit Security
- Customer may lock-down the customer lockable secured OTP by writing WRSCUR(write security register) com-
mand to set customer lock-down bit1 as "1".
Please refer to "Table 9. Security Register Definition" for security
register bit definition and "Table 3. 4K-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 4K-bit secured
OTP mode, array access is not allowed.
