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.
In Flash devices, this protection is removed by reprogramming the option. In this case, the
entire program memory is first automatically erased and the device can be reprogrammed.
Read-out protection selection depends on the device type:
