Comments • The priority of an interrupt line determines which line will be
acknowledged first in the event that more than one line is interrupting.
• For level, lower values have lower priority (level 1 is lower priority than
level 2).
• No parameter, or DEF (default) sets priority to 1.
•…PRIority1 through …PRIority7 specify the VXI interrupt lines 1
through 7.
• Sending PRIority without an [n] value specifies VXI interrupt line 1.
