Figure C-2. VXIbus Slot Configuration
When the VXI-1394 is installed in Slot 0, it becomes the VXIbus System
Controller. In this role, it has VXIbus Data Transfer Bus Arbiter circuitry
that accepts bus requests on all four VXIbus request levels, prioritizes the
requests, and grants the bus to the highest priority requester. As VXIbus
System Controller, the VXI-1394 also uses an onboard 16 MHz oscillator
to drive the 16 MHz VXIbus system clock.
