Hi all,

I set OTP on certain sectors in PF0. My expectation was that this sectors can be neither erased or programmed anymore once OTP was activated. However, when I clear PROCONOTP0, those protected were not protected anymore. Why is OTP programmable more than once?


Best regards,
Lina

Hi Lina,

If confirmation code is 0x43211234, this UCB is unlock state. Please set confirmation code to 0x57B5327F to make it permanent.
