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:

ICC interface
ICC (In-Circuit Communication) needs a minimum of four and up to six pins to be connected
to the programming tool (see

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.
