* This file provides firmware functions to manage the following |
|
7 |
* functionalities of the internal FLASH memory: |
|
8 |
* + Program operations functions |
|
9 |
* + Memory Control functions |
|
10 |

##### FLASH peripheral features ##### |
|
15 |
============================================================================== |
|
16 |
[..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses |
|
17 |
to the Flash memory. It implements the erase and program Flash memory operations |
|
18 |
and the read and write protection mechanisms. |
|
19 |
|
|
20 |
[..] The Flash memory interface accelerates code execution with a system of instruction |
|
21 |
prefetch. |
|
22 |
|
|
23 |
[..] The FLASH main features are: |
|
24 |
(+) Flash memory read operations |
|
25 |
(+) Flash memory program/erase operations |
|
26 |
(+) Read / write protections |
|
27 |
(+) Prefetch on I-Code |
|
28 |
(+) Option Bytes programming |
|
29 |
|
|
30 |
|
|
31 |
##### How to use this driver ##### |
|
32 |
============================================================================== |
|
33 |
[..] |
|
34 |
This driver provides functions and macros to configure and program the FLASH |
|
35 |
memory of all STM32F0xx devices. |
|
36 |
|
|
37 |
(#) FLASH Memory I/O Programming functions: this group includes all needed |
|
38 |
functions to erase and program the main memory: |
|
39 |
(++) Lock and Unlock the FLASH interface |
|
40 |
(++) Erase function: Erase page, erase all pages |
|
41 |
(++) Program functions: half word, word and doubleword |
|
42 |
(#) FLASH Option Bytes Programming functions: this group includes all needed |
|
43 |
functions to manage the Option Bytes: |
|
44 |
(++) Lock and Unlock the Option Bytes |
|
45 |
(++) Set/Reset the write protection |
|
46 |
(++) Set the Read protection Level |
|
47 |
(++) Program the user Option Bytes |
|
48 |
(++) Launch the Option Bytes loader |
|
49 |
(++) Erase Option Bytes |
|
50 |
(++) Program the data Option Bytes |
|
51 |
(++) Get the Write protection. |
|
52 |
(++) Get the user option bytes. |
|
53 |
|
|
54 |
(#) Interrupts and flags management functions : this group |
|
55 |
includes all needed functions to: |
|
56 |
(++) Handle FLASH interrupts |
|
57 |
(++) Wait for last FLASH operation according to its status |
|
58 |
(++) Get error flag status |
|
59 |
|
|
60 |
[..] In addition to these function, this driver includes a set of macros allowing |
|
61 |
to handle the following operations: |
|
62 |
|
|
63 |
(+) Set/Get the latency |
|
64 |
(+) Enable/Disable the prefetch buffer |
|
65 |
(+) Enable/Disable the FLASH interrupts |
|
66 |
(+) Monitor the FLASH flags status |
|
