- ##### Option Bytes Programming functions #####
- ==============================================================================
-
- [..] Any operation of erase or program should follow these steps:
- (#) Call the HAL_FLASH_OB_Unlock() function to enable the Flash option control
- register access.
- (#) Call following function to program the desired option bytes.
- (++) HAL_FLASHEx_OBProgram:
- - To Enable/Disable the desired sector write protection.
- - To set the desired read Protection Level.
- - To configure the user option Bytes: IWDG, STOP and the Standby.
- - To Set the BOR level.
- (#) Once all needed option bytes to be programmed are correctly written, call the
- HAL_FLASH_OB_Launch(void) function to launch the Option Bytes programming process.
- (#) Call the HAL_FLASH_OB_Lock() to disable the Flash option control register access (recommended
- to protect the option Bytes against possible unwanted operations).
-
- [..] Proprietary code Read Out Protection (PcROP):
- (#) The PcROP sector is selected by using the same option bytes as the Write
- protection (nWRPi bits). As a result, these 2 options are exclusive each other.
- (#) In order to activate the PcROP (change the function of the nWRPi option bits),
- the WPRMOD option bit must be activated.
- (#) The active value of nWRPi bits is inverted when PCROP mode is active, this
- means: if WPRMOD = 1 and nWRPi = 1 (default value), then the user sector "i"
- is read/write protected.
- (#) To activate PCROP mode for Flash sector(s), you need to call the following function:
- (++) HAL_FLASHEx_AdvOBProgram in selecting sectors to be read/write protected
- (++) HAL_FLASHEx_OB_SelectPCROP to enable the read/write protection

+ (#) Call following function to program the desired option bytes.

+ (#) Call the HAL_FLASH_OB_Lock() to disable the Flash option control register access (recommended
+ to protect the option Bytes against possible unwanted operations).
+
+ [..] Proprietary code Read Out Protection (PcROP):
+ (#) The PcROP sector is selected by using the same option bytes as the Write
+ protection (nWRPi bits). As a result, these 2 options are exclusive each other.
+ (#) In order to activate the PcROP (change the function of the nWRPi option bits),

+ (#) The active value of nWRPi bits is inverted when PCROP mode is active, this
+ means: if WPRMOD = 1 and nWRPi = 1 (default value), then the user sector "i"
+ is read/write protected.
