bogdanm 0:9b334a45a8ff 17 ##### FLASH peripheral features #####
bogdanm 0:9b334a45a8ff 18 ==============================================================================
bogdanm 0:9b334a45a8ff 19
bogdanm 0:9b334a45a8ff 20 [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses
bogdanm 0:9b334a45a8ff 21 to the Flash memory. It implements the erase and program Flash memory operations
bogdanm 0:9b334a45a8ff 22 and the read and write protection mechanisms.
bogdanm 0:9b334a45a8ff 23
bogdanm 0:9b334a45a8ff 24 [..] The Flash memory interface accelerates code execution with a system of instruction
bogdanm 0:9b334a45a8ff 25 prefetch.
bogdanm 0:9b334a45a8ff 26
bogdanm 0:9b334a45a8ff 27 [..] The FLASH main features are:
bogdanm 0:9b334a45a8ff 28 (+) Flash memory read operations
bogdanm 0:9b334a45a8ff 29 (+) Flash memory program/erase operations
bogdanm 0:9b334a45a8ff 30 (+) Read / write protections
bogdanm 0:9b334a45a8ff 31 (+) Prefetch on I-Code
bogdanm 0:9b334a45a8ff 32
bogdanm 0:9b334a45a8ff 33
bogdanm 0:9b334a45a8ff 34 ##### How to use this driver #####
bogdanm 0:9b334a45a8ff 35 ==============================================================================
bogdanm 0:9b334a45a8ff 36 [..]
bogdanm 0:9b334a45a8ff 37 This driver provides functions and macros to configure and program the FLASH
bogdanm 0:9b334a45a8ff 38 memory of all STM32F3xx devices. These functions are split in 3 groups:
bogdanm 0:9b334a45a8ff 39
bogdanm 0:9b334a45a8ff 40 (#) FLASH Memory I/O Programming functions: this group includes all needed
bogdanm 0:9b334a45a8ff 41 functions to erase and program the main memory:
bogdanm 0:9b334a45a8ff 42 (++) Lock and Unlock the FLASH interface
bogdanm 0:9b334a45a8ff 43 (++) Erase function: Erase page, erase all pages
bogdanm 0:9b334a45a8ff 44 (++) Program functions: half word and word
bogdanm 0:9b334a45a8ff 45
bogdanm 0:9b334a45a8ff 46 (#) Option Bytes Programming functions: this group includes all needed
bogdanm 0:9b334a45a8ff 47 functions to manage the Option Bytes:
bogdanm 0:9b334a45a8ff 48 (++) Lock and Unlock the Option Bytes
bogdanm 0:9b334a45a8ff 49 (++) Erase Option Bytes
bogdanm 0:9b334a45a8ff 50 (++) Set/Reset the write protection
bogdanm 0:9b334a45a8ff 51 (++) Set the Read protection Level
bogdanm 0:9b334a45a8ff 52 (++) Program the user Option Bytes
bogdanm 0:9b334a45a8ff 53 (++) Program the data Option Bytes
bogdanm 0:9b334a45a8ff 54 (++) Launch the Option Bytes loader
bogdanm 0:9b334a45a8ff 55
bogdanm 0:9b334a45a8ff 56 (#) Interrupts and flags management functions : this group
bogdanm 0:9b334a45a8ff 57 includes all needed functions to:
bogdanm 0:9b334a45a8ff 58 (++) Handle FLASH interrupts
bogdanm 0:9b334a45a8ff 59 (++) Wait for last FLASH operation according to its status
bogdanm 0:9b334a45a8ff 60 (++) Get error flag status
bogdanm 0:9b334a45a8ff 61
bogdanm 0:9b334a45a8ff 62 [..] In addition to these function, this driver includes a set of macros allowing
bogdanm 0:9b334a45a8ff 63 to handle the following operations:
bogdanm 0:9b334a45a8ff 64
bogdanm 0:9b334a45a8ff 65 (+) Set the latency
bogdanm 0:9b334a45a8ff 66 (+) Enable/Disable the prefetch buffer
bogdanm 0:9b334a45a8ff 67 (+) Enable/Disable the half cycle access
bogdanm 0:9b334a45a8ff 68 (+) Enable/Disable the FLASH interrupts
bogdanm 0:9b334a45a8ff 69 (+) Monitor the FLASH flags status
