Bit 1 = FMP_R Read-out protection

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 Section 4.5 on page 28 and the ST7

Flash Programming Reference Manual for more details.

Bit 0 = FMP_W Flash write protection

This option indicates if the Flash program memory is write protected.

0: Write protection off

Warning:

When the Flash write protection is selected, the program

memory (and the option bit itself) can never be erased or

programmed again.
