Part Number: AM3354

Hello :

I have some confuse in CPPI DMA  (In Ti.Reference_M, 16.3.9.9 USB Data Flow Using DMA) ,as follows:

1.Transmit USB Data Flow Using DMA:"After the USB packet is transferred,the USB 2.0 Core issue a TX DMA_req to the XDMA"-----where i can see this DMA_req ?

2.16.3.9.9.2.2:"it then asserts a DMA_req ti XDMA informing it that data is available in the endpoint FIFO"-----where i can see this DMA_req ?

Thanks
