ABSTRACT:
An apparatus controls a signal that indicates to a plug-in component board that it is to be connected to a 64-bit data path in a computer system. The apparatus comprises a timing circuit for receiving a reset signal and providing first and second complementary logical signals in response thereto. A selection switch receives the first and second logical signals as well as a control signal and outputs a third signal as determined by the logical level of the reset signal. A method involves generating first and second complementary signals from a reset signal, selecting between the first complementary signal and a control signal, and outputting a third signal, the logical value of the third signal being determined by the logical value of at least one of the reset signal and the control signal.
