sahilmgandhi 18:6a4db94011d3 17 ##### How to use this driver #####
sahilmgandhi 18:6a4db94011d3 18 ==============================================================================
sahilmgandhi 18:6a4db94011d3 19 [..] This driver provides functions to configure and program the FLASH memory
sahilmgandhi 18:6a4db94011d3 20 of all STM32F2xx devices. It includes
sahilmgandhi 18:6a4db94011d3 21 (#) FLASH Memory Erase functions:
sahilmgandhi 18:6a4db94011d3 22 (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
sahilmgandhi 18:6a4db94011d3 23 HAL_FLASH_Lock() functions
sahilmgandhi 18:6a4db94011d3 24 (++) Erase function: Erase sector, erase all sectors
sahilmgandhi 18:6a4db94011d3 25 (++) There are two modes of erase :
sahilmgandhi 18:6a4db94011d3 26 (+++) Polling Mode using HAL_FLASHEx_Erase()
sahilmgandhi 18:6a4db94011d3 27 (+++) Interrupt Mode using HAL_FLASHEx_Erase_IT()
sahilmgandhi 18:6a4db94011d3 28
sahilmgandhi 18:6a4db94011d3 29 (#) Option Bytes Programming functions: Use HAL_FLASHEx_OBProgram() to :
sahilmgandhi 18:6a4db94011d3 30 (++) Set/Reset the write protection
sahilmgandhi 18:6a4db94011d3 31 (++) Set the Read protection Level
sahilmgandhi 18:6a4db94011d3 32 (++) Set the BOR level
sahilmgandhi 18:6a4db94011d3 33 (++) Program the user Option Bytes
