PCI Bus Master Grant 1.
Internal PCI arbiter is enabled (PCI_CFN[1:0] = 11): Pin is an
output to grant a PCI device 1 control of the PCI Bus. (The
IXP1240 is PCI device 0 in this case)
Internal PCI arbiter is disabled (PCI_CFN[1:0] = 00): Pin is an
input that indicates that the IXP1240 can assert FRAME_L and
become the bus master. If the IXP1240 is idle when GNT_L[0] is
asserted, it parks the PCI Bus.
PCI Bus Master Request 1.
Internal PCI arbiter is enabled (PCI_CFN[1:0] = 11): Pin is an
input indicating an external PCI device is requesting use of the
PCI Bus.
Internal PCI arbiter is disabled (PCI_CFN[1:0] = 00): Pin is an
output indicating that the IXP1240 is requesting use of the PCI
Bus.
PCI Bus Master Grant 2.
Internal PCI arbiter is enabled (PCI_CFN[1:0] = 11): Pin is an
output to grant a PCI device 2 control of the PCI Bus (The
IXP1240 is PCI device 0 in this case).
When Internal PCI arbiter is disabled (PCI_CFN[1:0]=00,
GNT_L[1] should be connected to VDDX through a pullup resistor
of 10 KOhms.
PCI Bus Master Request 2.
Internal PCI arbiter is enabled (PCI_CFN[1:0] = 11): This input
indicates that PCI device 2 is requesting to take control of the PCI
Bus.
Is driven to an output high level when internal PCI arbiter is
disabled (PCI_CFN[1:0] = 00).
