| 25 | ##### FLASH peripheral features ##### |
| 26 | ============================================================================== |
| 27 | |
| 28 | [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses |
| 29 | to the Flash memory. It implements the erase and program Flash memory operations |
| 30 | and the read and write protection mechanisms. |
| 31 | |
| 32 | [..] The Flash memory interface accelerates code execution with a system of instruction |
| 33 | prefetch and cache lines. |
| 34 | |
| 35 | [..] The FLASH main features are: |
| 36 | (+) Flash memory read operations |
| 37 | (+) Flash memory program/erase operations |
| 38 | (+) Read / write protections |
| 39 | (+) Prefetch on I-Code |
| 40 | (+) 64 cache lines of 128 bits on I-Code |
| 41 | (+) 8 cache lines of 128 bits on D-Code |
| 42 | |
| 43 | |
| 44 | ##### How to use this driver ##### |
| 45 | ============================================================================== |
| 46 | [..] |
| 47 | This driver provides functions and macros to configure and program the FLASH |
| 48 | memory of all STM32F2xx devices. |
| 49 | |
| 50 | (#) FLASH Memory IO Programming functions: |
| 51 | (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and |
| 52 | HAL_FLASH_Lock() functions |
| 53 | (++) Program functions: byte, half word, word and double word |
| 54 | (++) There Two modes of programming : |
| 55 | (+++) Polling mode using HAL_FLASH_Program() function |
| 56 | (+++) Interrupt mode using HAL_FLASH_Program_IT() function |
| 57 | |
| 58 | (#) Interrupts and flags management functions : |
| 59 | (++) Handle FLASH interrupts by calling HAL_FLASH_IRQHandler() |
| 60 | (++) Wait for last FLASH operation according to its status |
| 61 | (++) Get error flag status by calling HAL_SetErrorCode() |
| 62 | |
| 63 | [..] |
| 64 | In addition to these functions, this driver includes a set of macros allowing |
| 65 | to handle the following operations: |
| 66 | (+) Set the latency |
| 67 | (+) Enable/Disable the prefetch buffer |
| 68 | (+) Enable/Disable the Instruction cache and the Data cache |
| 69 | (+) Reset the Instruction cache and the Data cache |
| 70 | (+) Enable/Disable the FLASH interrupts |
| 71 | (+) Monitor the FLASH flags status |
| 72 | |
