| mbed_official | 87:085cde657901 | 16 | ##### FLASH peripheral features ##### |
| mbed_official | 87:085cde657901 | 17 | ============================================================================== |
| mbed_official | 87:085cde657901 | 18 | |
| mbed_official | 87:085cde657901 | 19 | [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses |
| mbed_official | 87:085cde657901 | 20 | to the Flash memory. It implements the erase and program Flash memory operations |
| mbed_official | 87:085cde657901 | 21 | and the read and write protection mechanisms. |
| mbed_official | 87:085cde657901 | 22 | |
| mbed_official | 87:085cde657901 | 23 | [..] The Flash memory interface accelerates code execution with a system of instruction |
| mbed_official | 87:085cde657901 | 24 | prefetch and cache lines. |
| mbed_official | 87:085cde657901 | 25 | |
| mbed_official | 87:085cde657901 | 26 | [..] The FLASH main features are: |
| mbed_official | 87:085cde657901 | 27 | (+) Flash memory read operations |
| mbed_official | 87:085cde657901 | 28 | (+) Flash memory program/erase operations |
| mbed_official | 87:085cde657901 | 29 | (+) Read / write protections |
| mbed_official | 87:085cde657901 | 30 | (+) Prefetch on I-Code |
| mbed_official | 87:085cde657901 | 31 | (+) 64 cache lines of 128 bits on I-Code |
| mbed_official | 87:085cde657901 | 32 | (+) 8 cache lines of 128 bits on D-Code |
| mbed_official | 87:085cde657901 | 33 | |
| mbed_official | 87:085cde657901 | 34 | |
| mbed_official | 87:085cde657901 | 35 | ##### How to use this driver ##### |
| mbed_official | 87:085cde657901 | 36 | ============================================================================== |
| mbed_official | 87:085cde657901 | 37 | [..] |
| mbed_official | 87:085cde657901 | 38 | This driver provides functions and macros to configure and program the FLASH |
| mbed_official | 87:085cde657901 | 39 | memory of all STM32F4xx devices. |
| mbed_official | 87:085cde657901 | 40 | |
| mbed_official | 87:085cde657901 | 41 | (#) FLASH Memory IO Programming functions: |
| mbed_official | 87:085cde657901 | 42 | (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and |
| mbed_official | 87:085cde657901 | 43 | HAL_FLASH_Lock() functions |
| mbed_official | 87:085cde657901 | 44 | (++) Program functions: byte, half word, word and double word |
| mbed_official | 87:085cde657901 | 45 | (++) There Two modes of programming : |
| mbed_official | 87:085cde657901 | 46 | (+++) Polling mode using HAL_FLASH_Program() function |
| mbed_official | 87:085cde657901 | 47 | (+++) Interrupt mode using HAL_FLASH_Program_IT() function |
| mbed_official | 87:085cde657901 | 48 | |
| mbed_official | 87:085cde657901 | 49 | (#) Interrupts and flags management functions : |
| mbed_official | 87:085cde657901 | 50 | (++) Handle FLASH interrupts by calling HAL_FLASH_IRQHandler() |
| mbed_official | 87:085cde657901 | 51 | (++) Wait for last FLASH operation according to its status |
| mbed_official | 87:085cde657901 | 52 | (++) Get error flag status by calling HAL_SetErrorCode() |
| mbed_official | 87:085cde657901 | 53 | |
| mbed_official | 87:085cde657901 | 54 | [..] |
| mbed_official | 87:085cde657901 | 55 | In addition to these functions, this driver includes a set of macros allowing |
| mbed_official | 87:085cde657901 | 56 | to handle the following operations: |
| mbed_official | 87:085cde657901 | 57 | (+) Set the latency |
| mbed_official | 87:085cde657901 | 58 | (+) Enable/Disable the prefetch buffer |
| mbed_official | 87:085cde657901 | 59 | (+) Enable/Disable the Instruction cache and the Data cache |
| mbed_official | 87:085cde657901 | 60 | (+) Reset the Instruction cache and the Data cache |
| mbed_official | 87:085cde657901 | 61 | (+) Enable/Disable the FLASH interrupts |
| mbed_official | 87:085cde657901 | 62 | (+) Monitor the FLASH flags status |
