PCI Configuration Space

Specification Revision 1.0b) at the rising edge of RST#. Onboard logic

will sense the states of PCIXCAP and M66EN for all devices on the bus 2 and select the appropriate mode and clock frequency. Software can access

the MV64360 Configuration Registers to determine the PCI mode and clock frequency of PCI Bus 1 and PCI Bus 0. Refer to the MV64360 Data Sheet, listed in Appendix A, Related Documentation, for details.

Voltage Input/Output (VIO) is selected on PCI Bus 1 by the position of the PMC keying pins. Both sites should be set for the same VIO; that is, keyed identically. If 5V VIO is selected, PCI Bus 1 reverts to PCI mode at 33 MHz.

PCI Configuration Space

The MV64360 controls all PCI configuration space access from either the CPU or PCI busses. The IDSEL assignments for MVME6100 are shown on the following table:

Table 2-6. IDSEL Mapping for PCI Devices

	Device	PCI Address

PCI Bus 1	0b1_0100	AD20	PMC Slot 0 (SCSI controller also uses
			IDSEL AD20)

PCI Bus 1	0b1_0101	AD21	PMC Slot 0, Secondary PCI Agent,
			IPMC slot

PCI Bus 1	0b1_0110	AD22	PMC Slot 1

PCI Bus 1	0b1_0111	AD23	PMC Slot 1, Secondary PCI Agent
