phungductung 0:e87aa4c49e95 14 ##### Flash Extension features #####
phungductung 0:e87aa4c49e95 15 ==============================================================================
phungductung 0:e87aa4c49e95 16
phungductung 0:e87aa4c49e95 17 [..] Comparing to other previous devices, the FLASH interface for STM32F727xx/437xx and
phungductung 0:e87aa4c49e95 18 devices contains the following additional features
phungductung 0:e87aa4c49e95 19
phungductung 0:e87aa4c49e95 20 (+) Capacity up to 2 Mbyte with dual bank architecture supporting read-while-write
phungductung 0:e87aa4c49e95 21 capability (RWW)
phungductung 0:e87aa4c49e95 22 (+) Dual bank memory organization
phungductung 0:e87aa4c49e95 23 (+) PCROP protection for all banks
phungductung 0:e87aa4c49e95 24
phungductung 0:e87aa4c49e95 25 ##### How to use this driver #####
phungductung 0:e87aa4c49e95 26 ==============================================================================
phungductung 0:e87aa4c49e95 27 [..] This driver provides functions to configure and program the FLASH memory
phungductung 0:e87aa4c49e95 28 of all STM32F7xx devices. It includes
phungductung 0:e87aa4c49e95 29 (#) FLASH Memory Erase functions:
phungductung 0:e87aa4c49e95 30 (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
phungductung 0:e87aa4c49e95 31 HAL_FLASH_Lock() functions
phungductung 0:e87aa4c49e95 32 (++) Erase function: Erase sector, erase all sectors
phungductung 0:e87aa4c49e95 33 (++) There are two modes of erase :
phungductung 0:e87aa4c49e95 34 (+++) Polling Mode using HAL_FLASHEx_Erase()
phungductung 0:e87aa4c49e95 35 (+++) Interrupt Mode using HAL_FLASHEx_Erase_IT()
phungductung 0:e87aa4c49e95 36
phungductung 0:e87aa4c49e95 37 (#) Option Bytes Programming functions: Use HAL_FLASHEx_OBProgram() to :
phungductung 0:e87aa4c49e95 38 (++) Set/Reset the write protection
phungductung 0:e87aa4c49e95 39 (++) Set the Read protection Level
phungductung 0:e87aa4c49e95 40 (++) Set the BOR level
phungductung 0:e87aa4c49e95 41 (++) Program the user Option Bytes
phungductung 0:e87aa4c49e95 42 (#) Advanced Option Bytes Programming functions: Use HAL_FLASHEx_AdvOBProgram() to :
phungductung 0:e87aa4c49e95 43 (++) Extended space (bank 2) erase function
phungductung 0:e87aa4c49e95 44 (++) Full FLASH space (2 Mo) erase (bank 1 and bank 2)
phungductung 0:e87aa4c49e95 45 (++) Dual Boot activation
phungductung 0:e87aa4c49e95 46 (++) Write protection configuration for bank 2
phungductung 0:e87aa4c49e95 47 (++) PCROP protection configuration and control for both banks
phungductung 0:e87aa4c49e95 48
