FX2LP in manual mode
I work on Cy7C68013A FX2LP usb 2.0 HS controller.
I need to interface a cmos image sensor to the controller. The PCLK (pixel clock ) of the image sensor is interfaced to the IFCLK of the controller. The cmos image sensor emits data at every PCLK. The PCLK runs at around 40ns. I need to interface the PCLK with the IFCLK , so that I can collect the data at every 40ns to the controller.
This scenario can be implemented in synchronous auto mode. But I need to do some modifications on the data I receive. So, I would prefer to do this in manual mode.
Is it possible for the controller to read data in every 40ns. I would be reading the data and filling the buffer in TD_Poll().
The cmos image sensor continuously emits data at every 40ns irrespective of the controller processing. If the controller fails to grab data in every 40 ns, the data gets corrupted.
Please help me know if the time period 40ns is too small for the controller to grab data in subsequent TD_Poll() calls.
