In this configuration, a plug-in interface board in a computer is connected
to the VXI mainframe via one or more VXIbus extended controllers. The
computer then exerts overall control over VXIbus system operations.
A MXIbus master that does not arbitrate for the MXIbus after releasing
it until it detects the bus request signal inactive. This ensures that all
requesting devices are granted use of the bus.
