ASCII Overview and Commands

INTERRUPT:SETUP

Sets all interrupt parameters. This description also includes information on

the following commands which query the interrupt parameters individually:

INTERRUPT:MASK? gets the interrupt event mask.

INTERRUPT:PRIORITY? gets the VME interrupt line.

Command Syntax:

INTERRUPT:SETUP <intrNum>,<priority>,<mask>

IntrNum::=01

priority::=0 to 7

mask::=0 to 255

Query Syntax:

INTERRUPT:MASK?

INTERRUPT:PRIORITY?

Example Statements:

OUTPUT 70924;"Interrupt:setup 0,5,24"

OUTPUT 70924;"INTERRUPT:MASK?"

Description:

An E1437 has two independent interrupt generators, each capable of interrupting

on one of the seven VME interrupt lines when a status condition specified by a mask

occurs.

INTERRUPT:SETUP sets the interrupt mask, priority and which of the two interrupt

generators on the E1437 is to be used. The remaining INTERRUPT commands set or

query the mask and priority individually.

Parameter Definitions:

and 1.

ORing together the bits defined in bits 8 through 15 of the status register. The mask

parameter format is 0xMM00 where MM represents the maskable upper 8 bits. The

lower 8 bits cannot be used for generating interrupts, and therefore must be set to

zero in the function call.

values are 0 through 7. Specifying 0 turns the interrupt off, while 7 is the highest

priority.

Comments:

The mask is cleared during the interrupt acknowledge cycle. Therefore, the

command must be sent again in order to generate further interrupts.

Reset Values

priority=0, mask=0
