Figure 3-3. VXIbus Slot Configuration
When the VXI-MXI-2 is installed in Slot 0, it becomes the VMEbus
System Controller. In this role, it has VMEbus Data Transfer Bus Arbiter
circuitry that accepts bus requests on all four VMEbus request levels,
prioritizes the requests, and grants the bus to the highest priority requester.
As VMEbus System Controller, the VXI-MXI-2 also drives the 16 MHz
VMEbus system clock by an onboard 16 MHz oscillator.
