    Add a deterministic state transition when I customize AN75779?


      Hi Cypress,


      I am trying to customize the AN75779 to add in controls like snapshot or series of shots. 


      I use FPGA as data source in place of the image sensor. The current UVC state machine runs continuously. 


      When I implement a snapshot routine, is the following feasible? 


      1) IIC_Write to FPGA to stop FV/LV, Disable GPIF with CyU3PGpifDisable


      2) CyFxUvcAppGpifInit, CyU3PDmaMultiChannelReset, and CyU3PUsbFlushEp


      3) CyU3PDmaMultiChannelSetXfer, CyU3PGpifSMStart at START_SCK0


      4) IIC_Write to FPGA to capture frame and activate FV/LV into FX3.
