============================================================================== ##### FLASH peripheral features ##### ============================================================================== [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses to the Flash memory. It implements the erase and program Flash memory operations and the read and write protection mechanisms. [..] The Flash memory interface accelerates code execution with a system of instruction prefetch and cache lines. [..] The FLASH main features are: (+) Flash memory read operations (+) Flash memory program/erase operations (+) Read / write protections (+) Option bytes programming (+) Prefetch on I-Code (+) 32 cache lines of 4*64 bits on I-Code (+) 8 cache lines of 4*64 bits on D-Code (+) Error code correction (ECC) : Data in flash are 72-bits word (8 bits added per double word) ##### How to use this driver ##### ============================================================================== [..] This driver provides functions and macros to configure and program the FLASH memory of all STM32L4xx devices. (#) Flash Memory IO Programming functions: (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and HAL_FLASH_Lock() functions (++) Program functions: double word and fast program (full row programming) (++) There Two modes of programming : (+++) Polling mode using HAL_FLASH_Program() function (+++) Interrupt mode using HAL_FLASH_Program_IT() function (#) Interrupts and flags management functions : (++) Handle FLASH interrupts by calling HAL_FLASH_IRQHandler() (++) Callback functions are called when the flash operations are finished : HAL_FLASH_EndOfOperationCallback() when everything is ok, otherwise HAL_FLASH_OperationErrorCallback() (++) Get error flag status by calling HAL_GetError() (#) Option bytes management functions : (++) Lock and Unlock the option bytes using HAL_FLASH_OB_Unlock() and HAL_FLASH_OB_Lock() functions (++) Launch the reload of the option bytes using HAL_FLASH_Launch() function. In this case, a reset is generated [..] In addition to these functions, this driver includes a set of macros allowing to handle the following operations: (+) Set the latency (+) Enable/Disable the prefetch buffer (+) Enable/Disable the Instruction cache and the Data cache (+) Reset the Instruction cache and the Data cache (+) Enable/Disable the Flash power-down during low-power run and sleep modes (+) Enable/Disable the Flash interrupts (+) Monitor the Flash flags status
