It is around 550 - 900ns. Considering auto mode. In manual mode it would have dependency based on what the application firmware is doing.
You can use the many to one configuration is one way of working around the buffer switching issue.
The programming manual said 550 - 900 ns (in chapter about PPort)..,,there's another application notes about UVC said the break time is in "micro-seconds".
550-900ns is good enough for my application.. Thanks again.
In my application I use AUTO DMA and double buffering. But I can watch breaks up to 12µs while switching the DMA buffer. The minimum I can measure is 2.1µs. This results in a data rate of only 308MB/s using the 100MHz PCLK. Can you explain this? I use the SDK version 1.2.3
