Bus Request Level
Guidelines
• There are four bus request lines (BG0–BG3) from which one is
selected (Figure 1-3). Bus request line 3 has the highest priority, bus
request line 0 has the lowest priority.
• It is not necessary to change the bus request level setting (BG3) on
the AFG. (More information on the Data Transfer Bus can be found
in the C-Size VXIbus Systems Configuration Guide.)
