10.2 Endpoint description
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 reset state.
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
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 bytes long. Any of the
seven IN and seven OUT endpoints can separately be enabled or disabled. The endpoint
type (interrupt, isochronous or bulk) and packet size of these endpoints can individually be
configured, depending on the requirements of the application. Optional double buffering
increases the data throughput of these data endpoints.
