11.2 FLASH Firmware driver API description
The following section lists the various functions of the FLASH library.
11.2.1 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:
1. 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.
2. 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.
3. FLASH Option Bytes Programming functions: this group includes all needed functions
to manage the Option Bytes:
 Lock and Unlock the Flash Option bytes.
