摘要： A communications system may include a plurality of communications buses, at least one bus device connected to the plurality of communications buses, and a plurality of bus controllers for sending a plurality of bus enable signals to the at least one bus device. The at least one bus device may include selection circuitry for selecting one of the communications buses based upon the plurality of bus enable signals while being tolerant of an error on at least one of the bus enable signals. First and second bus enable signals may have a same value and may be generated by a primary bus controller upon receiving power. A third bus enable signal may be generated by a redundant bus controller upon receiving power.
