Abstract

A method for automatically terminating a bus that is dependent upon whether devices are coupled to ports of a device interface is disclosed. The method includes the steps of (a) generating a first sensing voltage having a voltage level equal to one of at least three levels; (b) generating a first control voltage having a fourth level when the voltage level of the first sensing voltage has a first predetermined logical relationship to a first reference voltage; and (c) terminating a first plurality of lines of the bus at the device interface when the first control voltage is equal to the fourth level. An apparatus suitable for implementing the above method is also disclosed.
