22.3
USB data transfers take place between host and a particular endpoint on an USB device.
The INCA-D supports multiple data transfer endpoints. The USB host treats
communications with any endpoint of the INCA-D independently from any other
endpoint. Such associations between the host software and a USB device endpoint are
called pipes. As an example, the INCA-D could have an endpoint supporting a pipe for
transporting B1-channel data from the host to the memory and another endpoint
supporting a pipe for transporting B1-channel data from the INCA-D to the host. The
USB architecture of the INCA-D comprehends all four basic types of data transfers, i.e.
Control, Isochronous, Interrupt and Bulk.

Function
Control data are used to configure devices, data transmission is
lossless. Control pipes are bidirectional, data transfer is possible
in both directions via one pipe. Endpoint 0 is always configured
as control endpoint with a maximum buffer length of 8 bytes. The
control endpoint can be configured to handle data packets of 64
bytes maximum length.
Isochronous data are continuous and real-time in creation and
consumption, such as voice data. In this case, real-time is
defined from frame to frame. Isochronous data transfer has the
highest priority, but is not always lossless.
Isochronous pipes are always unidirectional, so one endpoint
can be associated to an IN pipe or an OUT pipe. The INCA-D
supports up to 64 bytes.
Interrupt data are a small amount of data, which are transferred
every n frames, with n being programmable by the host. Data
delivery is lossless.
Interrupt pipes are always unidirectional pipes with selectable
direction (IN or OUT pipe), the maximum data packet length is
limited to 64 bytes.
Bulk data can be a larger amount of data, which can be split by
the host in several data packets within one frame. Data delivery
is lossless.
Bulk pipes are always unidirectional, so one endpoint can be
associated to an IN pipe or an OUT pipe. The maximum data
packet length is limited to 64 bytes.
