    Sample code for Advanced sector protection of S25FL512S Vol.2


      I previously asked here about Advanced Sector Protection. I have a new question.


      I want to use Password Sector Protection to prevent rewriting of the first 1 sector (256 KB).

      Should the start address of the sector be specified for the Address of PPB Program (PPBP:E3h) and PPB Read (PPBRD:E2h)?


      I think ”the start address of the sector"  is below, is it correct? :

         NOR flash in address space start address of sector 0 (for example, 0x2000 0000) + sector size (256KB) x offset for the number of sectors


      Do you have more detailed materials?

      I already check S25FL512S datasheet and AN200452, but I cannot understand setting value.
