The PMCspan expansion module connector, J6, is a 114-pin Mictor
connector. It is located near P2 on the primary side of the MVME2300SC.
Its interrupt lines are routed to the Raven MPIC.
The VMEbus interface is implemented with the CA91C042 Universe
ASIC. The Universe chip interfaces the 32/64-bit PCI local bus to the
VMEbus.
The Universe ASIC provides:
The PCI-bus-to-VMEbus interface
The VMEbus-to-PCI-bus interface
The DMA controller functions of the local VMEbus
The Universe chip includes Universe Control and Status Registers
(UCSRs) for interprocessor communications. It can provide the VMEbus
system controller functions as well. For detailed programming
information, refer to the Universe User's Manual and to the discussions in
the MVME2300 Series VME Processor Module Programmer's Reference
Guide.
