Hi all,
Can any body tell me what is the role of external DMA in any USB device??? I know that DMA interface with memory, endpoint buffers and micro controller, but how does the DMA helps in controlling memory to transfer the data and what are the signals the DMA receives to transfer the data between memory and endpoint buffers?
Please reply...
Thank you.
