##### Flash peripheral Extended features ##### | |
============================================================================== | |
[..] Comparing to other products, the FLASH interface for STM32L1xx | |
devices contains the following additional features | |
(+) Erase functions | |
(+) DATA_EEPROM memory management | |
(+) BOOT option bit configuration | |
(+) PCROP protection for all sectors | |
##### How to use this driver ##### | |
============================================================================== | |
[..] This driver provides functions to configure and program the FLASH memory | |
of all STM32L1xx. It includes: | |
(+) Full DATA_EEPROM erase and program management | |
(+) Boot activation | |
(+) PCROP protection configuration and control for all pages | |

##### Option Bytes Programming functions ##### | |
============================================================================== | |
[..] Any operation of erase or program should follow these steps: | |
(#) Call the @ref HAL_FLASH_OB_Unlock() function to enable the Flash option control | |
register access. | |
(#) Call following function to program the desired option bytes. | |
(++) @ref 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 | |
@ref HAL_FLASH_OB_Launch(void) function to launch the Option Bytes programming process. | |
(#) Call the @ref 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 SPRMOD option bit must be activated. | |
(#) The active value of nWRPi bits is inverted when PCROP mode is active, this | |
means: if SPRMOD = 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: | |
(++) @ref HAL_FLASHEx_AdvOBProgram in selecting sectors to be read/write protected | |
(++) @ref HAL_FLASHEx_OB_SelectPCROP to enable the read/write protection | |
(#) PcROP is available only in STM32L151xBA, STM32L152xBA, STM32L151xC, STM32L152xC & STM32L162xC devices. | |
