Abstract
A multi-drop bus input/output method and apparatus is disclosed. The apparatus comprises a multi-drop bus that has termination ends. The multi-drop bus also has a characteristic impedance. The multi-drop bus can be used for communication between devices. Devices that are attached to a termination end of the bus drive data onto the bus at the characteristic impedance. Devices that are attached to the bus, but not the termination ends, drive data onto the bus at one-half of the characteristic impedance. An end device terminates to ground with the characteristic impedance, and middle devices have high impedance, when not driving data.
