Hi all,

I'm using S25FL127S SPI NOR flash in my project. I read in the datasheet in section 7.6.3 that

" The Status Register 2 OTP bits can be changed using the WRR command with 24 input cycles. "

Does that mean I can change the OTP bits of SR2 back to 0 from 1? Please clarify.

Thanks & Regards,

Vinay

Hello,

Thank you for contacting Cypress Community Forum. OTP, may be written to "1" but, if the value is already "1", it cannot be written to "0", it will remain "1".

Thank you
