Read-Out Protection, when selected provides a protection against program memory
content extraction and against write access to Flash memory. Erasing the option bytes
when the FMP_R option is selected will cause the whole memory to be erased first,
and the device can be reprogrammed. Refer to
Flash Programming Reference Manual for more details.
0: Read-Out Protection off
1: Read-Out Protection on
This option indicates if the Flash program memory is write protected.
0: Write protection off
