Detailed Description
This file provides firmware functions to manage the following functionalities of the FLASH peripheral:
- Version
- V1.1.1
- Date
- 04-April-2014
- FLASH Interface configuration
- FLASH Memory Programming
- Option Bytes Programming
- Interrupts and flags management
===============================================================================
##### How to use this driver #####
===============================================================================
[..] This driver provides functions to configure and program the FLASH
memory of all STM32F30x devices. These functions are split in 4 groups:
(#) FLASH Interface configuration functions: this group includes the
management of following features:
(++) Set the latency.
(++) Enable/Disable the Half Cycle Access.
(++) Enable/Disable the prefetch buffer.
(#) FLASH Memory Programming functions: this group includes all needed
functions to erase and program the main memory:
(++) Lock and Unlock the FLASH interface.
(++) Erase function: Erase page, erase all pages.
(++) Program functions: Half Word and Word write.
(#) FLASH Option Bytes Programming functions: this group includes all
needed functions to manage the Option Bytes:
(++) Lock and Unlock the Flash Option bytes.
(++) Launch the Option Bytes loader
(++) Erase the Option Bytes
(++) Set/Reset the write protection
(++) Set the Read protection Level
(++) Program the user option Bytes
(++) Set/Reset the BOOT1 bit
(++) Enable/Disable the VDDA Analog Monitoring
(++) Enable/Disable the SRAM parity
(++) Get the user option bytes
(++) Get the Write protection
(++) Get the read protection status
(#) FLASH Interrupts and flags management functions: this group includes
all needed functions to:
(++) Enable/Disable the FLASH interrupt sources.
(++) Get flags status.
(++) Clear flags.
(++) Get FLASH operation status.
(++) Wait for last FLASH operation.- Attention
