AN2606 Rev65 Feb 2025 pattern 11 seems incorrect

I think the correct one should be nBOOT0_SEL(bit) = 0 as in previous version.

Please verify.

After reading your thread, I believe that U0 should be pattern 11 because RM0503 and in Option bytes in STM32CubeProgrammer show NBOOT_SEL bit 
However document  AN2606 Rev65 pattern 11 in the second condition should change nBoot0_SEL(bit) back to 0 as in previous document version.
