PSoC 5LP ARchitecture TRM mentions about circular DMA mode in which multiple TDs are chanined together and used in a circular manner. Is there any way to use to use circular DMA mode during usb communication? The application note says that DMA is configured with the first call to USBFS ReadOutEP or LoadInEP. So how do we specify multiple buffers which can be filled up by DMA in circular manner? Application note AN56377 gives an example of Auto DMA transfer with only a single buffer. Is there any example of using multiple DMA buffers in circular manner for USB communication?
