如何改变IFCONFIG寄存器值将操作模式从端口模式转变为从FIFO模式？

嗨，你的问题还不清楚。你的意思是问：改变IfCONFIG足以改变模式从PIO到奴隶FIFO模式吗？为了切换模式，需要更改IFCONFIG。除此之外，您还必须注意EPFIFO缓冲器的自动/手动配置以及PIO模式中使用的GPIOS是否与数据总线或从FIFO模式中使用的其他线路重合。感谢尼基尔

          Hi Your question is not clear. Do you mean to ask: Is changing the IFCONFIG enough to change the mode from PIO to Slave FIFO mode? For switching the mode, you need to change IFCONFIG. Apart from that, you will have to take care to auto/manual config of EPFIFO buffers and whether the gpios used in PIO mode coincide with data bus or other lines used in Slave FIFO mode. Thanks Nikhil   

我的意思是，如果我要在操作过程中从PIO模式转换为从FIFO模式，这是否可以应用？在其他操作中，我是否更改了ICONFIG寄存器值？

   I mean that if i wnat to change IFCONFIG from PIO mode to slave fifo mode during operation, is this can possible apply? Just i do change IFCONFIG register value during other operating?

你好，
您可以动态地从端口IO模式变为从FIFO模式。然而，这样做时，必须注意连接和其他引脚配置。在端口IO模式下，所有PosiPin都作为正常GPIOs。然而，它们在从FIFO模式中具有特定的功能，可以从TRM中找到。在从FIFO模式中，所有的接口连接都应该正确地进行，以确保正确工作。例如，如果选择外部IFCK，它必须在5 MHz的最小频率下自由运行。此外，为了为内部端点FIFO逻辑提供同步，必须在固件集IFCONFIG 7＝0之前存在外部IFCK源。
当做，

   Hi,
     
    You can change from the port IO mode to the slave fifo mode dynamically. However, whil doing so, you must take care of teh connections and other pin configurations. In port IO mode, all the portpins act as normal GPIOs. However, they have specific functionalities in the slave fifo mode, which can be found fro the TRM. While in slave fifo mode, all the interface connections should be properly done to ensure proper working. For example, say If an external IFCLK is chosen, it must be free-running at a minimum frequency of 5 MHz. In addition, in order to provide synchronization for the internal endpoint FIFO logic, the external IFCLK source must be present before the firmware sets IFCONFIG.7 = 0.

我想选择一个外部时钟，SOI有SETIFCONFIG。7＝0和IFCKIs 48 MHz的频率。虽然它不起作用，但是当IFCK来自FX2LP时，它工作得很好。为什么？

  I want to choose an external clock，So I have set IFCONFIG.7 = 0 and the frequency of the IFCLK is 48MHz. Though it dosen't work .But when the ifclk is from the fx2lp，it works well. Why?
