Device control is handled via the
control
port,
which
can
be
configured as either an I2C or SPI
compliant interface. The choice of
interface is specified during hardware
resets.

Data is organized in frames which are
transmitted at the system sampling
frequency. Frames contain source
and control information and are
further divided into sub-frames of 8
bytes fields. At the physical level, data
is transferred as serial bits with bi-
phase encoding.

The Digital Data Bus (D2B) is a
networking protocol for automotive
multimedia data communication
integrating digital audio, video and
other high data rate synchronous or
asynchronous signals, with the
control
data
for
network
management protocols and APIs.
The protocol enables robust single
cable
interconnection
and
compatible interoperation of in-car
AV multimedia and ITS devices, such
as Radio Head Units, CD Changer,
CD-ROM, GPS Navigation, Voice
Control, Car Telephones, TV and
others.
