4.3.1
Readout protection
Readout 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.
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.
