7.12 PCI Arbitration Assignments
The integrated PCI/X arbiters internal to the MPC8540 and the PCI6520 bridges provide PCI
arbitration for the MVME3100. The MPC8540 provides arbitration support for itself and the
four PCI-X devices on PCI bus A.
The PCI6520 secondary PCI/X interface arbiters support external bus masters in addition to the
PCI6520. One secondary arbiter provides arbitration for the PMC sites on PCI bus B, and the
other provides arbitration for the PMCspan and USB host controller on PCI bus C.
The arbitration assignments on the MVME3100 are shown in the follow table so that software
may set arbiter priority assignments if necessary.
VME Controller TSi148 0x10E3 0x0148
sATA Controller Sil3124A 0x1095 0x3124
USB Controller μPD720101 0x1033 0x0035
