MPC Bus and PCI Bus Arbitration

The MV64360 ASIC supplies these functions. Refer to the MV64360 Data

Sheet, listed in Appendix A, Related Documentation, for details.

PCI Bus 0 and PCI Bus 1 Local Buses

The PCI devices on the MVME6100 are: the MV64360 ASIC, the

PMCspan bridge PCI6520, the Tsi148 ASIC, PMCspan slot and the PMC

Slots.

PCI Mode/Frequency Selection

The MVME6100 PCI Bus 0 bus is be set to PCI-X and 133 MHz for maximum performance. Onboard logic drives the PCI-X initialization pattern, as defined by the PCI-X Addendum to the PCI Local Bus Specification Revision 1.0a at the rising edge of RST#.

The MVME6100 dynamically determines the mode and frequency of the

PCI Bus 1 (defined by the PCI-X Addendum to the PCI Local Bus
