Memory protection
There are two different types of memory protection: Read-Out Protection and Write/Erase
Protection which can be applied individually.
Read-out protection
Read-Out Protection, when selected provides a protection against program memory content
extraction and against write access to Flash memory. Even if no protection can be
considered as totally unbreakable, the feature provides a very high level of protection for a
general purpose microcontroller.
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. Write/Erase Protection is enabled through the FMP_W
bit in the option byte.
Once set, Write/Erase Protection can never be removed. A write-protected Flash
device is no longer reprogrammable.
Related documentation
For details on Flash programming and ICC protocol, refer to the ST7 Flash Programming
Reference Manual and to the ST7 ICC Protocol Reference Manual
In Flash devices, this protection is removed by reprogramming the option. In this case,
the program memory is automatically erased and the device can be reprogrammed.
The read-out protection is enabled and removed through the FMP_R bit in the option
byte.
