phungductung 0:e87aa4c49e95 15 ==============================================================================
phungductung 0:e87aa4c49e95 16 ##### FLASH peripheral features #####
phungductung 0:e87aa4c49e95 17 ==============================================================================
phungductung 0:e87aa4c49e95 18
phungductung 0:e87aa4c49e95 19 [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses
phungductung 0:e87aa4c49e95 20 to the Flash memory. It implements the erase and program Flash memory operations
phungductung 0:e87aa4c49e95 21 and the read and write protection mechanisms.
phungductung 0:e87aa4c49e95 22
phungductung 0:e87aa4c49e95 23 [..] The Flash memory interface accelerates code execution with a system of instruction
phungductung 0:e87aa4c49e95 24 prefetch and cache lines.
phungductung 0:e87aa4c49e95 25
phungductung 0:e87aa4c49e95 26 [..] The FLASH main features are:
phungductung 0:e87aa4c49e95 27 (+) Flash memory read operations
phungductung 0:e87aa4c49e95 28 (+) Flash memory program/erase operations
phungductung 0:e87aa4c49e95 29 (+) Read / write protections
phungductung 0:e87aa4c49e95 30 (+) Prefetch on I-Code
phungductung 0:e87aa4c49e95 31 (+) 64 cache lines of 128 bits on I-Code
phungductung 0:e87aa4c49e95 32 (+) 8 cache lines of 128 bits on D-Code
phungductung 0:e87aa4c49e95 33
phungductung 0:e87aa4c49e95 34 ##### How to use this driver #####
phungductung 0:e87aa4c49e95 35 ==============================================================================
phungductung 0:e87aa4c49e95 36 [..]
phungductung 0:e87aa4c49e95 37 This driver provides functions and macros to configure and program the FLASH
phungductung 0:e87aa4c49e95 38 memory of all STM32F7xx devices.
phungductung 0:e87aa4c49e95 39
phungductung 0:e87aa4c49e95 40 (#) FLASH Memory IO Programming functions:
phungductung 0:e87aa4c49e95 41 (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
phungductung 0:e87aa4c49e95 42 HAL_FLASH_Lock() functions
phungductung 0:e87aa4c49e95 43 (++) Program functions: byte, half word, word and double word
phungductung 0:e87aa4c49e95 44 (++) There Two modes of programming :
phungductung 0:e87aa4c49e95 45 (+++) Polling mode using HAL_FLASH_Program() function
phungductung 0:e87aa4c49e95 46 (+++) Interrupt mode using HAL_FLASH_Program_IT() function
phungductung 0:e87aa4c49e95 47
phungductung 0:e87aa4c49e95 48 (#) Interrupts and flags management functions :
phungductung 0:e87aa4c49e95 49 (++) Handle FLASH interrupts by calling HAL_FLASH_IRQHandler()
phungductung 0:e87aa4c49e95 50 (++) Wait for last FLASH operation according to its status
phungductung 0:e87aa4c49e95 51 (++) Get error flag status by calling HAL_SetErrorCode()
phungductung 0:e87aa4c49e95 52 [..]
phungductung 0:e87aa4c49e95 53 In addition to these functions, this driver includes a set of macros allowing
phungductung 0:e87aa4c49e95 54 to handle the following operations:
phungductung 0:e87aa4c49e95 55 (+) Set the latency
phungductung 0:e87aa4c49e95 56 (+) Enable/Disable the prefetch buffer
phungductung 0:e87aa4c49e95 57 (+) Enable/Disable the Instruction cache and the Data cache
phungductung 0:e87aa4c49e95 58 (+) Reset the Instruction cache and the Data cache
phungductung 0:e87aa4c49e95 59 (+) Enable/Disable the FLASH interrupts
phungductung 0:e87aa4c49e95 60 (+) Monitor the FLASH flags status
phungductung 0:e87aa4c49e95 61 [..]
phungductung 0:e87aa4c49e95 62 (@) For any Flash memory program operation (erase or program), the CPU clock frequency
phungductung 0:e87aa4c49e95 63 (HCLK) must be at least 1MHz.
phungductung 0:e87aa4c49e95 64 (@) The contents of the Flash memory are not guaranteed if a device reset occurs during
phungductung 0:e87aa4c49e95 65 a Flash memory operation.
phungductung 0:e87aa4c49e95 66 (@) Any attempt to read the Flash memory while it is being written or erased, causes the
phungductung 0:e87aa4c49e95 67 bus to stall. Read operations are processed correctly once the program operation has
phungductung 0:e87aa4c49e95 68 completed. This means that code or data fetches cannot be performed while a write/erase
phungductung 0:e87aa4c49e95 69 operation is ongoing.
