Datasheet

The ChannelAddresses output by the Controller for each logical channel are used in normal data transport and can
be statically or dynamically assigned. T
o support dynamic configuration of MediaLB Devices, a unique
DeviceAddress must be assigned to all MediaLB Devices before startup. DeviceAddresses allow the External Host
Controller (EHC) and MediaLB Controller to dynamically determine which Devices exist on the bus. At the request of
a MediaLB Device (e.g. EHC), the Controller scans for DeviceAddresses in the System Channel. Once a Device is
detected, a ChannelAddress for each logical channel can be assigned.
The DeviceAddress, ChannelAddress, Command, and RxStatus structures are described in the Link Layer section.
48.2 Embedded Characteristics
• Support of all MOST data transport methods: synchronous stream data, asynchronous packet data, control
message data, and isochronous data
• Multiple clock rates supported
• Scalable data rate for all MOST Network data transport methods
• A frame synchronization pattern (FRAMESYNC) enables easy Device synchronization to MOST Networks
• Dedicated system-broadcast channel for administration
• Support of MediaLB Controller to MediaLB Device transfers and inter-MediaLB Devices transfers
• Broadcast support from one transmitter to multiple receivers for synchronous stream data
