7 * @brief FLASH HAL module driver.
8 * This file provides firmware functions to manage the following
9 * functionalities of the internal FLASH memory:
10 * + Program operations functions
11 * + Memory Control functions
12 * + Peripheral Errors functions
13 *
14 @verbatim
15 ==============================================================================
16 ##### FLASH peripheral features #####
17 ==============================================================================
18
19 [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses
20 to the Flash memory. It implements the erase and program Flash memory operations
21 and the read and write protection mechanisms.
22
23 [..] The Flash memory interface accelerates code execution with a system of instruction
24 prefetch and cache lines.
25
26 [..] The FLASH main features are:
27 (+) Flash memory read operations
28 (+) Flash memory program/erase operations
29 (+) Read / write protections
30 (+) Prefetch on I-Code
31 (+) 64 cache lines of 128 bits on I-Code
32 (+) 8 cache lines of 128 bits on D-Code
33
34 ##### How to use this driver #####
35 ==============================================================================
36 [..]
37 This driver provides functions and macros to configure and program the FLASH
38 memory of all STM32F7xx devices.
39
40 (#) FLASH Memory IO Programming functions:
41 (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
42 HAL_FLASH_Lock() functions
43 (++) Program functions: byte, half word, word and double word
44 (++) There Two modes of programming :
45 (+++) Polling mode using HAL_FLASH_Program() function
46 (+++) Interrupt mode using HAL_FLASH_Program_IT() function
47
48 (#) Interrupts and flags management functions :
49 (++) Handle FLASH interrupts by calling HAL_FLASH_IRQHandler()
50 (++) Wait for last FLASH operation according to its status
51 (++) Get error flag status by calling HAL_SetErrorCode()
52 [..]
53 In addition to these functions, this driver includes a set of macros allowing
54 to handle the following operations:
55 (+) Set the latency
56 (+) Enable/Disable the prefetch buffer
57 (+) Enable/Disable the Instruction cache and the Data cache
58 (+) Reset the Instruction cache and the Data cache
59 (+) Enable/Disable the FLASH interrupts
60 (+) Monitor the FLASH flags status
61 [..]
62 (@) For any Flash memory program operation (erase or program), the CPU clock frequency
63 (HCLK) must be at least 1MHz.
64 (@) The contents of the Flash memory are not guaranteed if a device reset occurs during
65 a Flash memory operation.
66 (@) Any attempt to read the Flash memory while it is being written or erased, causes the
67 bus to stall. Read operations are processed correctly once the program operation has
68 completed. This means that code or data fetches cannot be performed while a write/erase
69 operation is ongoing.
