It implements the erase and program Flash memory operations - and the read and write protection mechanisms. - - [..] The Flash memory interface accelerates code execution with a system of instruction - prefetch and cache lines. - - [..] The FLASH main features are: - (+) Flash memory read operations - (+) Flash memory program/erase operations - (+) Read / write protections - (+) Prefetch on I-Code - (+) 64 cache lines of 128 bits on I-Code - (+) 8 cache lines of 128 bits on D-Code - - ##### How to use this driver ##### - ============================================================================== - [..] - This driver provides functions and macros to configure and program the FLASH - memory of all STM32F7xx devices. - - (#) FLASH Memory IO Programming functions: - (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and - HAL_FLASH_Lock() functions - (++) Program functions: byte, half word, word and double word - (++) There Two modes of programming : - (+++) Polling mode using HAL_FLASH_Program() function - (+++) Interrupt mode using HAL_FLASH_Program_IT() function - - (#) Interrupts and flags management functions : - (++) Handle FLASH interrupts by calling HAL_FLASH_IRQHandler() - (++) Wait for last FLASH operation according to its status - (++) Get error flag status by calling HAL_SetErrorCode() - [..] - In addition to these functions, this driver includes a set of macros allowing - to handle the following operations: - (+) Set the latency - (+) Enable/Disable the prefetch buffer - (+) Enable/Disable the Instruction cache and the Data cache - (+) Reset the Instruction cache and the Data cache - (+) Enable/Disable the FLASH interrupts - (+) Monitor the FLASH flags status - [..] - (@) For any Flash memory program operation (erase or program), the CPU clock frequency - (HCLK) must be at least 1MHz. - (@) The contents of the Flash memory are not guaranteed if a device reset occurs during - a Flash memory operation. - (@) Any attempt to read the Flash memory while it is being written or erased, causes the - bus to stall. Read operations are processed correctly once the program operation has - completed. This means that code or data fetches cannot be performed while a write/erase - operation is ongoing. - - @endverbatim - ****************************************************************************** - * @attention - * - * <h2><center>© COPYRIGHT(c) 2015 STMicroelectronics</center></h2> - * - * Redistribution and use in source and binary forms, with or without modification, - * are permitted provided that the following conditions are met: - * 1.
