0: LSI clock is not available as CPU clock source
1: LSI clock is available as CPU clock source
0: IWDG Independent watchdog activated by software
1: IWDG Independent watchdog activated by hardware
0: WWDG window watchdog activated by software
1: WWDG window watchdog activated by hardware
0: No reset generated on halt if WWDG active
1: Reset generated on halt if WWDG active
0: External crystal connected to OSCIN/OSCOUT
1: External clock signal on OSCIN
0: LSI clock source selected for AWU
1: HSE clock with prescaler selected as clock source for for AWU
00: 24 MHz to 128 kHz prescaler
01: 16 MHz to 128 kHz prescaler
10: 8 MHz to 128 kHz prescaler
11: 4 MHz to 128 kHz prescaler
This configures the stabilisation time to 0.5, 8, 128, and 2048 HSE
cycles with corresponding option byte values of E1h, D2h, B4h, and 00h.
0101: TMU disabled (permanent ROP).
Any other value: TMU enabled.
This option configures the number of wait states inserted when reading
from the Flash/data EEPROM memory.
0: No wait state
1: One wait state
Temporary unprotection key: Must be different from 00h or FFh
Temporary unprotection key: Must be different from 00h or FFh
Temporary unprotection key: Must be different from 00h or FFh
Temporary unprotection key: Must be different from 00h or FFh
