| bogdanm | 0:9b334a45a8ff | 262 | (#) Call the HAL_FLASH_OB_Unlock() function to enable the Flash option control |

| bogdanm | 0:9b334a45a8ff | 266 | - To Enable/Disable the desired sector write protection. |
| bogdanm | 0:9b334a45a8ff | 267 | - To set the desired read Protection Level. |
| bogdanm | 0:9b334a45a8ff | 268 | - To configure the user option Bytes: IWDG, STOP and the Standby. |
| bogdanm | 0:9b334a45a8ff | 269 | - To Set the BOR level. |
| bogdanm | 0:9b334a45a8ff | 270 | (#) Once all needed option bytes to be programmed are correctly written, call the |
| bogdanm | 0:9b334a45a8ff | 271 | HAL_FLASH_OB_Launch(void) function to launch the Option Bytes programming process. |
