Abstract
A slew rate control circuit of a bus includes two connection devices that are adapted to be coupled to two voltage supplies. The connection devices are connected to the bus by a select terminal of a signal application device. The signal application device has first and second positions which apply first and second amounts of resistance to the bus depending on the voltage on the select terminal. If an expansion board is adapted to be coupled to the bus, a different voltage is applied on the select terminal. A method for controlling a slew rate includes applying a resistive load to a bus corresponding to the number of logic circuits in a computer system. The number of logic circuits within the computer is varied by either adding or removing a logic circuit. A second resistive load is selected to be applied to the bus after the number of logic circuits in the computer system has been varied. The selection of a second resistance enables the amount of slew rate to be reduced.
