mbed_official 87:085cde657901 15 ==============================================================================
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
