bogdanm 0:9b334a45a8ff 7 * @brief Extended FLASH HAL module driver.
bogdanm 0:9b334a45a8ff 8 * This file provides firmware functions to manage the following
bogdanm 0:9b334a45a8ff 9 * functionalities of the FLASH extension peripheral:
bogdanm 0:9b334a45a8ff 10 * + Extended programming operations functions

bogdanm 0:9b334a45a8ff 13 ==============================================================================
bogdanm 0:9b334a45a8ff 14 ##### Flash Extension features #####
bogdanm 0:9b334a45a8ff 15 ==============================================================================
bogdanm 0:9b334a45a8ff 16
bogdanm 0:9b334a45a8ff 17 [..] Comparing to other previous devices, the FLASH interface for STM32F427xx/437xx and
bogdanm 0:9b334a45a8ff 18 STM32F429xx/439xx devices contains the following additional features
bogdanm 0:9b334a45a8ff 19
bogdanm 0:9b334a45a8ff 20 (+) Capacity up to 2 Mbyte with dual bank architecture supporting read-while-write
bogdanm 0:9b334a45a8ff 21 capability (RWW)
bogdanm 0:9b334a45a8ff 22 (+) Dual bank memory organization
bogdanm 0:9b334a45a8ff 23 (+) PCROP protection for all banks
bogdanm 0:9b334a45a8ff 24
bogdanm 0:9b334a45a8ff 25 ##### How to use this driver #####
bogdanm 0:9b334a45a8ff 26 ==============================================================================
bogdanm 0:9b334a45a8ff 27 [..] This driver provides functions to configure and program the FLASH memory
bogdanm 0:9b334a45a8ff 28 of all STM32F427xx/437xx andSTM32F429xx/439xx devices. It includes
bogdanm 0:9b334a45a8ff 29 (#) FLASH Memory Erase functions:
bogdanm 0:9b334a45a8ff 30 (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
bogdanm 0:9b334a45a8ff 31 HAL_FLASH_Lock() functions
bogdanm 0:9b334a45a8ff 32 (++) Erase function: Erase sector, erase all sectors
bogdanm 0:9b334a45a8ff 33 (++) There are two modes of erase :
bogdanm 0:9b334a45a8ff 34 (+++) Polling Mode using HAL_FLASHEx_Erase()
bogdanm 0:9b334a45a8ff 35 (+++) Interrupt Mode using HAL_FLASHEx_Erase_IT()
bogdanm 0:9b334a45a8ff 36
bogdanm 0:9b334a45a8ff 37 (#) Option Bytes Programming functions: Use HAL_FLASHEx_OBProgram() to :
bogdanm 0:9b334a45a8ff 38 (++) Set/Reset the write protection
bogdanm 0:9b334a45a8ff 39 (++) Set the Read protection Level
bogdanm 0:9b334a45a8ff 40 (++) Set the BOR level
bogdanm 0:9b334a45a8ff 41 (++) Program the user Option Bytes
bogdanm 0:9b334a45a8ff 42 (#) Advanced Option Bytes Programming functions: Use HAL_FLASHEx_AdvOBProgram() to :
bogdanm 0:9b334a45a8ff 43 (++) Extended space (bank 2) erase function
bogdanm 0:9b334a45a8ff 44 (++) Full FLASH space (2 Mo) erase (bank 1 and bank 2)
bogdanm 0:9b334a45a8ff 45 (++) Dual Boot activation
bogdanm 0:9b334a45a8ff 46 (++) Write protection configuration for bank 2
bogdanm 0:9b334a45a8ff 47 (++) PCROP protection configuration and control for both banks
bogdanm 0:9b334a45a8ff 48
