bcostm 6:e1d9da7fe856 3 * @file stm32746g_discovery_qspi.c
bcostm 6:e1d9da7fe856 4 * @author MCD Application Team

Jerome Coutant 8:56384bddaba5 6 * @date 30-December-2016
bcostm 6:e1d9da7fe856 7 * @brief This file includes a standard driver for the N25Q128A QSPI
bcostm 6:e1d9da7fe856 8 * memory mounted on STM32746G-Discovery board.
bcostm 6:e1d9da7fe856 9 @verbatim
bcostm 6:e1d9da7fe856 10 ==============================================================================
bcostm 6:e1d9da7fe856 11 ##### How to use this driver #####
bcostm 6:e1d9da7fe856 12 ==============================================================================
bcostm 6:e1d9da7fe856 13 [..]
bcostm 6:e1d9da7fe856 14 (#) This driver is used to drive the N25Q128A QSPI external
bcostm 6:e1d9da7fe856 15 memory mounted on STM32746G-Discovery board.
bcostm 6:e1d9da7fe856 16
bcostm 6:e1d9da7fe856 17 (#) This driver need a specific component driver (N25Q128A) to be included with.
bcostm 6:e1d9da7fe856 18
bcostm 6:e1d9da7fe856 19 (#) Initialization steps:
bcostm 6:e1d9da7fe856 20 (++) Initialize the QPSI external memory using the BSP_QSPI_Init() function. This
bcostm 6:e1d9da7fe856 21 function includes the MSP layer hardware resources initialization and the
bcostm 6:e1d9da7fe856 22 QSPI interface with the external memory.
bcostm 6:e1d9da7fe856 23
bcostm 6:e1d9da7fe856 24 (#) QSPI memory operations
bcostm 6:e1d9da7fe856 25 (++) QSPI memory can be accessed with read/write operations once it is
bcostm 6:e1d9da7fe856 26 initialized.
bcostm 6:e1d9da7fe856 27 Read/write operation can be performed with AHB access using the functions
bcostm 6:e1d9da7fe856 28 BSP_QSPI_Read()/BSP_QSPI_Write().
bcostm 6:e1d9da7fe856 29 (++) The function BSP_QSPI_GetInfo() returns the configuration of the QSPI memory.
bcostm 6:e1d9da7fe856 30 (see the QSPI memory data sheet)
bcostm 6:e1d9da7fe856 31 (++) Perform erase block operation using the function BSP_QSPI_Erase_Block() and by
bcostm 6:e1d9da7fe856 32 specifying the block address. You can perform an erase operation of the whole
bcostm 6:e1d9da7fe856 33 chip by calling the function BSP_QSPI_Erase_Chip().
bcostm 6:e1d9da7fe856 34 (++) The function BSP_QSPI_GetStatus() returns the current status of the QSPI memory.
bcostm 6:e1d9da7fe856 35 (see the QSPI memory data sheet)
