O As outputs for the bidirectional initiator ready, these signals operate as described below.
I Initialization device select. The initialization device select signal is an input signal on this PCI controller.
I As inputs for the bidirectional initiator ready, these signals operate as described below.
disabled PCI_GNT0 is an input signal. Note that PCI_GNT[ n ] is a point-to-point signal. Every master
has its own bus grant signal.
Also, note that these signals are also used as reset configuration signals as described in
“Power-On Reset Configuration."
It is used as a chip select during configuration read and write transactions.
