Flash program memory
In flash devices, this protection is removed by reprogramming the option. In this case,
program memory is automatically erased, and the device can be reprogrammed.
Readout protection selection depends on the device type:
In Flash devices it is enabled and removed through the FMP_R bit in the option byte.
In ROM devices it is enabled by mask option specified in the option list.
4.5.2
Flash Write/Erase protection
Write/erase protection, when set, makes it impossible to both overwrite and erase program
memory. Its purpose is to provide advanced security to applications and prevent any change
being made to the memory content.
Warning:
Once set, Write/erase protection can never be removed. A
write-protected flash device is no longer reprogrammable.
Write/erase protection is enabled through the FMP_W bit in the option byte.
