A BUS INTERFACE AND METHOD FOR CONVEYING MULTI-LEVEL COMMUNICATION SIGNALS BETWEEN A COMMUNICATION BUS AND A DEVICE COUPLED TO A COMMUNICATION BUS

摘要

A bus interface and corresponding method is provided for conveying communication signals supporting multiple modes, where at least two of the modes have distinct operational communication signal levels. The bus interface is adapted to convert the communication signals between communication signals having distinct signal levels, and communication signals having compatible signal levels. Where in at least some instances, the conveyed communication signals are converted from communication signals having distinct signal levels to communication signals having compatible signal levels, and then back to communication signals having distinct signal levels, after the communication signals having compatible signal levels are transmitted and received via one or more associated communication paths.
