Hi-Speed USB OTG controller
If bit DMA_XFER_OK in the DMA Interrupt Reason register is asserted, it means that the
transfer counter has reached zero and the DMA transfer is successfully stopped.
If bit INT_EOT in the DMA Interrupt Reason register is set, it indicates that a short or
empty packet is received. This means that DMA transfer terminated. Normally, for an OUT
transfer, it means that remote host wishes to terminate the DMA transfer.
If both the bits DMA_XFER_OK and INT_EOT are set, it means that the transfer counter
reached zero and the last packet of the transfer is a short packet. Therefore, the DMA
transfer is successfully stopped.
Setting bit GDMA Stop in the DMA Command register (address: 0230h) will force the
DMA to stop and bit GDMA_STOP in the DMA Interrupt Reason register (address: 0250h)
will be set to indicate this event.
Setting bit Reset DMA in the DMA Command register (address: 0230h) will force the DMA
to stop and initialize the DMA core to its power-on state.
10.2 Endpoint description
Each USB peripheral is logically composed of several independent endpoints. An
endpoint acts as a terminus of a communication flow between the USB host and the USB
peripheral. At design time, each endpoint is assigned a unique endpoint identifier; see
Table 92
. The combination of the peripheral address (given by the host during
enumeration), the endpoint number, and the transfer direction allows each endpoint to be
uniquely referenced.
The peripheral controller has 8 kB of internal FIFO memory, which is shared among the
enabled USB endpoints. The two control endpoints are fixed 64 B long. Any of the 7 IN
and 7 OUT endpoints can be separately enabled or disabled. The endpoint type (interrupt,
isochronous or bulk) and packet size of these endpoints can be individually configured,
depending on the requirements of the application. Optional double buffering increases the
data throughput of these data endpoints.
