:INTerrupt:PRIority[n] DIAGnostic:INTerrupt:PRIority[n] [< level>] gives a priority level to the VXI

interrupt line specified by [n] in …PRIority[n].

level numeric 1 through 7| MIN| MAX| DEF none

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.

• This command has no effect if only one interrupt is to be set up.

• Related Commands: DIAG:INT:ACT, DIAG:INT:SETup[n],

DIAG:INT:RESP?

Example Setup, set a priority, and wait for VXI interrupt response on line 2.

DIAG:INT:PRI2 5 handle interrupt on line 2

DIAG:INT:PRI2 5 set priority to 5 on line 2

. code which will

. initiate an action

. resulting in an interrupt

DIAG:INT:RESP? Read the acknowledge response

:INTerrupt:PRIority[n]? DIAGnostic:INTerrupt:PRIority[n]? Returns the current priority level set for

the VXI interrupt line specified by [n] in …PRIority[n]?.

Comments •…PRIority?1 through …PRIority?7 specify the VXI interrupt lines 1

through 7.

• Sending PRIority? without an [n] value specifies VXI interrupt line 1.
