NI-VISA Driver with Interrupt detection

[XiaolinAtUB]

Hello everyone,

I am new to PCI and PCI driver, encounter an problem when use the NI-VISA to program a PCI driver with the interrupt detection.

Here is the situation:

This PCI card is made of two chips : the PCI9030 pci bridge chip and ET1100 chip (the local chip that connected to PCI9030). The memory of ET1100 is mapped 1:1 to the PCI9030 memory starting at BAR2. Now I want the PCI card generates an interruption when the content of register at offset 0x221 changes.  

I add the interrupt detection (see the figure above or the attachment), interruption removal and disarm following the guide "Using the NI-VISA Driver Wizard and NI-VISA to Develop a PXI(e)/PCI(e) Driver in Windows". However, when I completed and installed this driver in the LabVIEW RT OS, the system can recognize the card, but cannot generate the interruption when the register at offset 0x221 changes, therefore does anyone tell me the reason ? Or tell me how to program this driver using NI-VISA?

Any suggestions is welcome.

And Thank you in advance!
