Comments • When an interrupt occurs and has been acknowledged, the response is
read with the DIAGnostic:INTerrupt:RESPonse? command.
• If an interrupt occurs on a VXIbus backplane interrupt line and the
interrupt acknowledgement has not been enabled, there is no interrupt
acknowledgement response. The interrupt will be held off until the
interrupt acknowledge is enabled by either the DIAG:INT:ACT
command or DIAG:INT:RESP? command.
• ON or 1 enable interrupt acknowledgement. OFF or 0 disables interrupt
acknowledgement.
• Bit 8 in the Operation Status register can be used to indicate when an
interrupt has been acknowledged. See chapter 6 for more details about
this register.
• Interrupt acknowledgement must be re-enabled every time an interrupt is
acknowledged
• Related Commands: DIAG:INT:PRIority[n], DIAG:INT:RESP?,
DIAG:INT:SET[n]
• *RST Condition: DIAG:INT:ACTivate OFF (for all lines)
Example Enable an Interrupt Acknowledgement on Line 2.
DIAG:INT:SET2 Set up interrupt line 2
DIAG:INT:ACT ON Enable interrupt to be
acknowledged
:INTerrupt:SETup[n] DIAGnostic:INTerrupt:SETup[n] < mode> specifies that an interrupt on VXI
backplane interrupt line [n] will be serviced by the System Instrument service
routine (DIAGnostic:INTerrupt commands) rather than the operating system
service routine.
