Default
value
Readout 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
0: Read-out protection off
1: Read-out protection on
This option indicates if the Flash program memory is write protected.
Warning: When this option is selected, the program memory (and the option bit itself)
can never be erased or programmed again.
0: Write protection off
1: Write protection on
This option bit selects the number of CPU cycles inserted during the reset phase and
when exiting Halt mode. For resonator oscillators, it is advised to select 4096 due to the
long crystal stabilization time.
0: Reset phase with 4096 CPU cycles
1: Reset phase with 256 CPU cycles
When the internal RC oscillator is not selected (Option OSC=1), these option bits
select the range of the resonator oscillator current source or the external clock source.
