Hi ,

I want to apply static write protection on both banks. i have used syscnfig to configure specific area in flash. below is the configuration i have done in sysconfig.

This configuration i have done to write protect first 80Kb of both banks. Dose clearing lower 4 bit of staticWriteProtectionMainHigh has same impact as clearing `staticWriteProtectionMainLow` ?

FLASHSWP0 = 0x0

FLASHSWP1 = FFFFFC00

FLASHSWP2 = FFFFFC00

Does clearing the lower four bits of FLASHSWP1.staticWriteProtectionMainHigh have the same effect as clearing the corresponding bits in FLASHSWP0.staticWriteProtectionMainLow?

For FLASHSWP0 and FLASHSWP1 , they take care of Flash bank 0. The lower 32kB of Bank 0 are taken care by FLASHSWP0.

And FLASHSWP1 's lower 4 bit will be ignored.

You can see the detailed description in syscfg, corresponding "?" button I marked with red ▢

Ok then what about bank 1? why value for FLASHSWP1 and FLASHSWP2 is same?

You can read the syscfg details to get the answer, these are a little difference between FLASHSWP1 and FLASHSWP2 because of FLASHSWP0
