Hi, I have a question about "Write Protection" in Option Byte. Is it possible to write protection only for one page instead of one block? In STM Programmer I see only 64 blocks (WRPx). One block corresponding to 16 pages (4096kB of memory).

[KPode.1]

I would like to choose one page like in STM32 ST-LINK Utility:

Welcome, @KPode.1​, to the community!

Which STM32 are you talking about in the first case and which in the second?

Regards

I have already found an information in datasheet about writing protection with 4Kbytes granularity for STM32L151xC. I used different STM32 in my comparison, like you said.

Thank you for your help.
