30.1 Overview

The MediaLB (MLB) is a three wire interface that maps all the Media Oriented Systems Transport (MOST) Network data types (transport methods) into a single low-cost, scalable, and standardized hardware interface between a MediaLB Controller and at least one other MediaLB Device. The MediaLB module in this MCU is restricted to the functionality of a Media DEVICE only and not that of a Media CONTROLLER. Therefore, MLBCLK is an input clock signal from the MediaLB CONTROLLER in the MOST network. The use of MediaLB simplifies the hardware interface, reduces the pin count, and facilitates the design of modular reusable hardware. From a software development perspective, the use of MediaLB relieves the system developer from the complexity of the MOST Network, which simplifies software development and enables the design of reusable software for different applications. This simplified, standardized interface shortens time-to-market and makes software maintenance effortless.

The link layer and three different physical layers are defined as part of this specification. The physical layer section describes pin configurations, operating speeds, and bus topology. The link layer section describes the compliance of the signaling and addressing protocol.
