●

OPT1 =

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 the ST7 Flash Programming Reference

Manual and Section 4.5: Memory protection for more details

0: Read-out protection off

1: Read-out protection on

●

OPT0 =

FMP_W Flash write protection

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

0: Write protection off

1: Write protection on

Warning:

When this option is selected, the program memory (and the

option bit itself) can never be erased or programmed again.
