DIAGnostic:INTerrupt:RESPonse?

:INTerrupt:RESPonse?	DIAGnostic:INTerrupt:RESPonse? Returns the interrupt acknowledge
	response (STATUS/ID word) from the highest priority VXI interrupt line.
Comments	• The value returned is the response from the interrupt acknowledge cycle
	(STATUS/ID word) of a device interrupting on one of the interrupt lines
	set up with the DIAG:INT:SET[n] command.
	• Bits 0 through 7 of the STATUS/ID word are the interrupting device’s
	logical address. Bits 8 through 15 are Cause/Status bits. Bits 16 through
	31 (D32 Extension) are not read by the System Instrument.
	• If only bits 0 through 7 are used by the device (bits 8 - 15 are FF), the
	logical address can be determined by adding 256 to the value returned by
	DIAG:INT:RESP?. If bits 0 - 15 are used, the logical address address is
	determined by adding 65536 to the value returned (if the number
	returned is negative.
	• Only the interrupt lines previously configured with the
	DIAG:INT:SET[n] commands generate responses for this command.
	• If there are interrupts on multiple lines when this command is received,
	or when the acknowledgement was enabled with DIAG:INT:ACT, the
	response data returned will be from the line with the highest priority set
	using the DIAG:INT:PRI [n] command.
	• If interrupt acknowledge has not been enabled with DIAG:INT:ACT,
	then it will be enabled by DIAG:INT:RESP?. System Instrument
	execution is halted until the interrupt acknowledgement response is
	received.
	• DIAG:INT:WAIT? can also be used to wait for the interrupt response.
