Hi expert,

Can I set a password locations of a zone have all 128 bits as zeros(ALL_0) to make the zone becomes permanently secure?
If I set Z1_GRABSECT as ALL_0,can i modify the register again to unlock the zone?

Regards,

Sibo

Hi Sibo,

Yes you can use a password of all 0s to make a zone permanently secure.

If you do this, you will no longer be able to update the USER OTP to change your security settings.

If you set GRABSECT as all 0s, all securable flash will become inaccessible, which will block all instruction fetches to code stored in these memories as well as any data reads/writes.

Let me know if you have any further questions.
