2	PCI Arbitration Assignments for MV64360 ASIC
2
	PCI arbitration is performed by the MV64360 ASIC. The MV64360

	integrates two PCI arbiters, one for each PCI interface (PCI Bus 0/1). Each
	arbiter can handle up to six external agents plus one internal agent (PCI
	Bus 0/1 master). The internal PCI arbiter REQ#/GNT# signals are
	multiplexed on the MV64360 MPP pins. The internal PCI arbiter is
	disabled by default (the MPP pins function as general purpose inputs).
	Software will configure the MPP pins to function as request/grant pairs for
	the internal PCI arbiter.
	The arbitration assignments on MVME6100 are as follows:

PCI Bus 1 Local Bus PMC Expansion Slots

Two PMC slots reside on the PCI Bus 1 local bus. The presence of PMCs can be positively determined by reading System Status Register 3. The INTA#, INTB#, INTC#, and INTD# from the PMC slots are routed by the MVME6100 as follows:
