About whether the UTest NVM sector can be an OTP zone

[rujunzhou]

您好：
现在有一个问题，我们现在有一个要求，需要有一些数据写入OTP区域，目前看手册，有一个UTest NVM扇区，这个区域可以作为OTP区域来存储用户离厂的一些信息吗？如果是这样，如何？

期待回复
非常感谢

Hello,

Hello:
Now there is a problem, we now have a requirement that some data needs to be written into the OTP area. Currently, according to the manual, there is a UTest NVM sector. Can this area be used as the OTP area to store some information about the user leaving the factory? If so, how?

Yes, the OTP has user space. For programming it please refer to the DCF records section in reference manual of your device.

The principle of writing of DCF is the same but the addresses vary between different devices.

Best regards,

Peter
