| mbed_official | 237:f3da66175598 | 16 | ============================================================================== |
| mbed_official | 237:f3da66175598 | 17 | ##### FLASH peripheral features ##### |
| mbed_official | 237:f3da66175598 | 18 | ============================================================================== |
| mbed_official | 237:f3da66175598 | 19 | |
| mbed_official | 237:f3da66175598 | 20 | [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses |
| mbed_official | 237:f3da66175598 | 21 | to the Flash memory. It implements the erase and program Flash memory operations |
| mbed_official | 237:f3da66175598 | 22 | and the read and write protection mechanisms. |
| mbed_official | 237:f3da66175598 | 23 | |
| mbed_official | 237:f3da66175598 | 24 | [..] The Flash memory interface accelerates code execution with a system of instruction |
| mbed_official | 237:f3da66175598 | 25 | prefetch. |
| mbed_official | 237:f3da66175598 | 26 | |
| mbed_official | 237:f3da66175598 | 27 | [..] The FLASH main features are: |
| mbed_official | 237:f3da66175598 | 28 | (+) Flash memory read operations |
| mbed_official | 237:f3da66175598 | 29 | (+) Flash memory program/erase operations |
| mbed_official | 237:f3da66175598 | 30 | (+) Read / write protections |

| mbed_official | 237:f3da66175598 | 32 | |
| mbed_official | 237:f3da66175598 | 33 | |
| mbed_official | 237:f3da66175598 | 34 | ##### How to use this driver ##### |
| mbed_official | 237:f3da66175598 | 35 | ============================================================================== |
| mbed_official | 237:f3da66175598 | 36 | [..] |
| mbed_official | 237:f3da66175598 | 37 | This driver provides functions and macros to configure and program the FLASH |
| mbed_official | 237:f3da66175598 | 38 | memory of all STM32F3xx devices. These functions are split in 3 groups: |
| mbed_official | 237:f3da66175598 | 39 | |

| mbed_official | 237:f3da66175598 | 60 | (++) Get error flag status |
| mbed_official | 237:f3da66175598 | 61 | |
| mbed_official | 237:f3da66175598 | 62 | [..] In addition to these function, this driver includes a set of macros allowing |
| mbed_official | 237:f3da66175598 | 63 | to handle the following operations: |
| mbed_official | 237:f3da66175598 | 64 | |
