bogdanm 0:9b334a45a8ff 15 ==============================================================================
bogdanm 0:9b334a45a8ff 16 ##### FLASH peripheral features #####
bogdanm 0:9b334a45a8ff 17 ==============================================================================
bogdanm 0:9b334a45a8ff 18 [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses
bogdanm 0:9b334a45a8ff 19 to the Flash memory. It implements the erase and program Flash memory operations
bogdanm 0:9b334a45a8ff 20 and the read and write protection mechanisms.
bogdanm 0:9b334a45a8ff 21
bogdanm 0:9b334a45a8ff 22 [..] The Flash memory interface accelerates code execution with a system of instruction
bogdanm 0:9b334a45a8ff 23 prefetch.
bogdanm 0:9b334a45a8ff 24
bogdanm 0:9b334a45a8ff 25 [..] The FLASH main features are:
bogdanm 0:9b334a45a8ff 26 (+) Flash memory read operations
bogdanm 0:9b334a45a8ff 27 (+) Flash memory program/erase operations
bogdanm 0:9b334a45a8ff 28 (+) Read / write protections
bogdanm 0:9b334a45a8ff 29 (+) Prefetch on I-Code
bogdanm 0:9b334a45a8ff 30 (+) Option Bytes programming
bogdanm 0:9b334a45a8ff 31
bogdanm 0:9b334a45a8ff 32
bogdanm 0:9b334a45a8ff 33 ##### How to use this driver #####
bogdanm 0:9b334a45a8ff 34 ==============================================================================
bogdanm 0:9b334a45a8ff 35 [..]
bogdanm 0:9b334a45a8ff 36 This driver provides functions and macros to configure and program the FLASH
bogdanm 0:9b334a45a8ff 37 memory of all STM32F0xx devices.
bogdanm 0:9b334a45a8ff 38
bogdanm 0:9b334a45a8ff 39 (#) FLASH Memory I/O Programming functions: this group includes all needed
