>Does anyone know why the PCI 2.1 specification defines the REQ# and
>GNT# signals as bidirectional tri-state (section 2.2.4, page 11)? Is
>this just an artifact of the signal type definitions in section 2.1 on
>page 8 or is there an obvious reason that I am missing? Since these
>signals are defined as point-to-point, there is no obvious reason for
>any device other than a central resource to ever drive GNT#.
