bogdanm	0:9b334a45a8ff	274
bogdanm	0:9b334a45a8ff	275	[..] Any operation of erase or program should follow these steps:
bogdanm	0:9b334a45a8ff	276	(#) Call the HAL_FLASH_OB_Unlock() function to enable the Flash option control
bogdanm	0:9b334a45a8ff	277	register access.
bogdanm	0:9b334a45a8ff	278	(#) Call following function to program the desired option bytes.
bogdanm	0:9b334a45a8ff	279	(++) HAL_FLASHEx_OBProgram:
bogdanm	0:9b334a45a8ff	280	- To Enable/Disable the desired sector write protection.
bogdanm	0:9b334a45a8ff	281	- To set the desired read Protection Level.
bogdanm	0:9b334a45a8ff	282	- To configure the user option Bytes: IWDG, STOP and the Standby.
bogdanm	0:9b334a45a8ff	283	- To Set the BOR level.
bogdanm	0:9b334a45a8ff	284	(#) Once all needed option bytes to be programmed are correctly written, call the
bogdanm	0:9b334a45a8ff	285	HAL_FLASH_OB_Launch(void) function to launch the Option Bytes programming process.
bogdanm	0:9b334a45a8ff	286	(#) Call the HAL_FLASH_OB_Lock() to disable the Flash option control register access (recommended
bogdanm	0:9b334a45a8ff	287	to protect the option Bytes against possible unwanted operations).
bogdanm	0:9b334a45a8ff	288
bogdanm	0:9b334a45a8ff	289	[..] Proprietary code Read Out Protection (PcROP):
bogdanm	0:9b334a45a8ff	290	(#) The PcROP sector is selected by using the same option bytes as the Write
bogdanm	0:9b334a45a8ff	291	protection (nWRPi bits). As a result, these 2 options are exclusive each other.
bogdanm	0:9b334a45a8ff	292	(#) In order to activate the PcROP (change the function of the nWRPi option bits),
bogdanm	0:9b334a45a8ff	293	the SPRMOD option bit must be activated.
bogdanm	0:9b334a45a8ff	294	(#) The active value of nWRPi bits is inverted when PCROP mode is active, this
bogdanm	0:9b334a45a8ff	295	means: if SPRMOD = 1 and nWRPi = 1 (default value), then the user sector "i"
bogdanm	0:9b334a45a8ff	296	is read/write protected.
bogdanm	0:9b334a45a8ff	297	(#) To activate PCROP mode for Flash sector(s), you need to call the following function:
bogdanm	0:9b334a45a8ff	298	(++) HAL_FLASHEx_AdvOBProgram in selecting sectors to be read/write protected
bogdanm	0:9b334a45a8ff	299	(++) HAL_FLASHEx_OB_SelectPCROP to enable the read/write protection
bogdanm	0:9b334a45a8ff	300	(#) PcROP is available only in STM32L151xBA, STM32L152xBA, STM32L151xC, STM32L152xC & STM32L162xC devices.
