bogdanm 0:9b334a45a8ff 16 ##### FLASH peripheral features #####
bogdanm 0:9b334a45a8ff 17 ==============================================================================
bogdanm 0:9b334a45a8ff 18
bogdanm 0:9b334a45a8ff 19 [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses
bogdanm 0:9b334a45a8ff 20 to the Flash memory. It implements the erase and program Flash memory operations
bogdanm 0:9b334a45a8ff 21 and the read and write protection mechanisms.
bogdanm 0:9b334a45a8ff 22
bogdanm 0:9b334a45a8ff 23 [..] The Flash memory interface accelerates code execution with a system of instruction
bogdanm 0:9b334a45a8ff 24 prefetch and cache lines.
bogdanm 0:9b334a45a8ff 25
bogdanm 0:9b334a45a8ff 26 [..] The FLASH main features are:
bogdanm 0:9b334a45a8ff 27 (+) Flash memory read operations
bogdanm 0:9b334a45a8ff 28 (+) Flash memory program/erase operations
bogdanm 0:9b334a45a8ff 29 (+) Read / write protections
bogdanm 0:9b334a45a8ff 30 (+) Prefetch on I-Code
bogdanm 0:9b334a45a8ff 31 (+) 64 cache lines of 128 bits on I-Code
bogdanm 0:9b334a45a8ff 32 (+) 8 cache lines of 128 bits on D-Code
bogdanm 0:9b334a45a8ff 33
bogdanm 0:9b334a45a8ff 34
bogdanm 0:9b334a45a8ff 35 ##### How to use this driver #####
bogdanm 0:9b334a45a8ff 36 ==============================================================================
bogdanm 0:9b334a45a8ff 37 [..]
bogdanm 0:9b334a45a8ff 38 This driver provides functions and macros to configure and program the FLASH
bogdanm 0:9b334a45a8ff 39 memory of all STM32F4xx devices.
bogdanm 0:9b334a45a8ff 40
bogdanm 0:9b334a45a8ff 41 (#) FLASH Memory IO Programming functions:
bogdanm 0:9b334a45a8ff 42 (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
bogdanm 0:9b334a45a8ff 43 HAL_FLASH_Lock() functions
bogdanm 0:9b334a45a8ff 44 (++) Program functions: byte, half word, word and double word
bogdanm 0:9b334a45a8ff 45 (++) There Two modes of programming :
bogdanm 0:9b334a45a8ff 46 (+++) Polling mode using HAL_FLASH_Program() function
bogdanm 0:9b334a45a8ff 47 (+++) Interrupt mode using HAL_FLASH_Program_IT() function
bogdanm 0:9b334a45a8ff 48
bogdanm 0:9b334a45a8ff 49 (#) Interrupts and flags management functions :
bogdanm 0:9b334a45a8ff 50 (++) Handle FLASH interrupts by calling HAL_FLASH_IRQHandler()
bogdanm 0:9b334a45a8ff 51 (++) Wait for last FLASH operation according to its status
bogdanm 0:9b334a45a8ff 52 (++) Get error flag status by calling HAL_SetErrorCode()
bogdanm 0:9b334a45a8ff 53
bogdanm 0:9b334a45a8ff 54 [..]
bogdanm 0:9b334a45a8ff 55 In addition to these functions, this driver includes a set of macros allowing
bogdanm 0:9b334a45a8ff 56 to handle the following operations:
bogdanm 0:9b334a45a8ff 57 (+) Set the latency
bogdanm 0:9b334a45a8ff 58 (+) Enable/Disable the prefetch buffer
bogdanm 0:9b334a45a8ff 59 (+) Enable/Disable the Instruction cache and the Data cache
bogdanm 0:9b334a45a8ff 60 (+) Reset the Instruction cache and the Data cache
bogdanm 0:9b334a45a8ff 61 (+) Enable/Disable the FLASH interrupts
bogdanm 0:9b334a45a8ff 62 (+) Monitor the FLASH flags status
bogdanm 0:9b334a45a8ff 63
