/**
* @file xspi_numonyx_flash_quad_example.c
*
* This file contains a design example using the SPI driver (XSpi) and axi_qspi
* device with a Numonyx quad serial flash device in the interrupt mode.
* This example erases a Sector, writes to a Page within the Sector, reads back
* from that Page and compares the data.
*
* This example  has been tested with an N25Q128 device on KC705 and ZC770
* board. The bytes per page (PAGE_SIZE) in N25Q128 is 256.
*
* @note
*
* None.

* <pre>
* MODIFICATION HISTORY:
*
* Ver   Who  Date     Changes
* ----- ---- -------- -----------------------------------------------
* 1.00a bss  08/08/12 First release
* 3.04a bss  02/11/13 Modified to use ScuGic in case of Zynq (CR#683510)
* 4.2   ms   01/23/17 Added fmsh_print statement in main function to
*                     ensure that "Successfully ran" and "Failed" strings
*                     are available in all examples. This is a fix for
*                     CR-965028.
*       ms   04/05/17 Modified Comment lines to follow doxygen rules.
