怎么使用SPI配置FPGA然后启用32位从设备FIFO

你好，
从“编程EZ-USB®FX3μC处理器端口作为同步从FIFO”的应用模式来看，如果选择SPI，则不支持32位数据总线宽度。启动后，我使用SPI（GPIO（53）-SPILSCK和GPIO（56）-SPIXMOSI）来配置FPGA，然后使GPFI到32位从FIFO模式，显然是可行的。在固件运行时，我想再次用SPI接口重新配置FPGA，但在那个时候，GPIF是32位从FIFO模式，我可以停止GPIF或切换到16位模式，使用SPI重新配置FPGA，SWtiTCH到32位奴隶FIFO吗？
谢谢您！

  Hi,
    From the application mode of "Programming EZ-USB® FX3™ Processor Port as Synchronous Slave FIFO", 32 Bit data bus width is not supported if SPI is selected. After bootup, I use SPI (GPIO[53] - SPI_SCK and GPIO[56] - SPI_MOSI) to configure FPGA, then I enable GPFI to 32-bit slave FIFO mode, it is obviously doable. During firmware runtime, I want to re-configure FPGA with SPI interface again, but at that monent, GPIF is 32-bit slave FIFO mode, Can I stop GPIF or switch to 16-bit mode, using SPI re-configure FPGA, and swtich to 32-bit slave FIFO again?
    Thank you!
