18.2 FLASH Firmware driver API description
18.2.1 FLASH peripheral features
The Flash memory interface manages CPU AHB I-Code and D-Code accesses to the
Flash memory. It implements the erase and program Flash memory operations and the
read and write protection mechanisms.
The Flash memory interface accelerates code execution with a system of instruction
prefetch and cache lines.
The FLASH main features are:
Flash memory read operations
Flash memory program/erase operations
Read / write protections
Prefetch on I-Code
64 cache lines of 128 bits on I-Code
8 cache lines of 128 bits on D-Code
18.2.2 How to use this driver
This driver provides functions and macros to configure and program the FLASH memory of
all STM32F2xx devices.
