| mbed_official | 235:685d5f11838f | 16 | ##### FLASH peripheral features ##### |
| mbed_official | 235:685d5f11838f | 17 | ============================================================================== |
| mbed_official | 235:685d5f11838f | 18 | |
| mbed_official | 235:685d5f11838f | 19 | [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses |
| mbed_official | 235:685d5f11838f | 20 | to the Flash memory. It implements the erase and program Flash memory operations |
| mbed_official | 235:685d5f11838f | 21 | and the read and write protection mechanisms. |
| mbed_official | 235:685d5f11838f | 22 | |
| mbed_official | 235:685d5f11838f | 23 | [..] The Flash memory interface accelerates code execution with a system of instruction |
| mbed_official | 235:685d5f11838f | 24 | prefetch and cache lines. |
| mbed_official | 235:685d5f11838f | 25 | |
| mbed_official | 235:685d5f11838f | 26 | [..] The FLASH main features are: |
| mbed_official | 235:685d5f11838f | 27 | (+) Flash memory read operations |
| mbed_official | 235:685d5f11838f | 28 | (+) Flash memory program/erase operations |
| mbed_official | 235:685d5f11838f | 29 | (+) Read / write protections |
| mbed_official | 235:685d5f11838f | 30 | (+) Prefetch on I-Code |
| mbed_official | 235:685d5f11838f | 31 | (+) 64 cache lines of 128 bits on I-Code |
| mbed_official | 235:685d5f11838f | 32 | (+) 8 cache lines of 128 bits on D-Code |
| mbed_official | 235:685d5f11838f | 33 | |
| mbed_official | 235:685d5f11838f | 34 | |
| mbed_official | 235:685d5f11838f | 35 | ##### How to use this driver ##### |
| mbed_official | 235:685d5f11838f | 36 | ============================================================================== |
| mbed_official | 235:685d5f11838f | 37 | [..] |
| mbed_official | 235:685d5f11838f | 38 | This driver provides functions and macros to configure and program the FLASH |
| mbed_official | 235:685d5f11838f | 39 | memory of all STM32F4xx devices. |
| mbed_official | 235:685d5f11838f | 40 | |
| mbed_official | 235:685d5f11838f | 41 | (#) FLASH Memory IO Programming functions: |
| mbed_official | 235:685d5f11838f | 42 | (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and |
| mbed_official | 235:685d5f11838f | 43 | HAL_FLASH_Lock() functions |
| mbed_official | 235:685d5f11838f | 44 | (++) Program functions: byte, half word, word and double word |
| mbed_official | 235:685d5f11838f | 45 | (++) There Two modes of programming : |
| mbed_official | 235:685d5f11838f | 46 | (+++) Polling mode using HAL_FLASH_Program() function |
| mbed_official | 235:685d5f11838f | 47 | (+++) Interrupt mode using HAL_FLASH_Program_IT() function |
| mbed_official | 235:685d5f11838f | 48 | |
| mbed_official | 235:685d5f11838f | 49 | (#) Interrupts and flags management functions : |

| mbed_official | 235:685d5f11838f | 52 | (++) Get error flag status by calling HAL_SetErrorCode() |
| mbed_official | 235:685d5f11838f | 53 | |
| mbed_official | 235:685d5f11838f | 54 | [..] |
| mbed_official | 235:685d5f11838f | 55 | In addition to these functions, this driver includes a set of macros allowing |
| mbed_official | 235:685d5f11838f | 56 | to handle the following operations: |
| mbed_official | 235:685d5f11838f | 57 | (+) Set the latency |
| mbed_official | 235:685d5f11838f | 58 | (+) Enable/Disable the prefetch buffer |
