ABSTRACT:
In a computer system having a computer bus drive circuit capable of providing drive current to an individual line of a computer bus coupled thereto, a circuit for determining a proper level for the drive current and a method of making such determination. The circuit comprises: (1) a detection circuit, coupled to the individual line of the bus, for monitoring a response of the individual line of the bus to changes in state thereof during an operation of the computer system and providing an indication of the response and (2) a drive current establishment circuit, coupled between the detection circuit and the computer bus drive circuit, for establishing the proper level for the drive current in response to the indication produced by the detection circuit during an operation of the computer system.
