Abstract

Apparatus for permitting any of a plurality of driver circuits to control a select lead. In the preferred embodiment, the plurality of drivers are in separate peripheral component interconnect (PCI) host bridges. The drivers when active are in one of two low impedance states. A resistor whose impedance is substantially less than the high impedance of a driver when in the inactive state is connected to ground and pulls the voltage on the select lead toward ground when none of the drivers connected to the select lead are active. Advantageously, a plurality of drivers can control a single select lead, and only a short time is required as a guard interval between the time that two different drivers control the select lead.
