Enabling PXI/PCI interrupt handling within an NI-VISA application is a two-step process. First, you must specify how your device detects a pending interrupt. Second, you must specify how to acknowledge a pending interrupt. The NI-VISA Driver Wizard will guide you through the process of enabling NI-VISA to perform these two steps.

  • Add a step before—Adds a register operation prior to the currently selected step.
  • Add a step afters—Adds a register operation immediately following the currently selected step.
  • Edit a step—Allows you to modify the properties of the currently selected register operation.
  • Remove a step—Removes the currently selected step from the sequence of register operations.
  • Select sequence—Selects a transaction sequence to view or modify.
  • Add sequence—Adds a new transaction sequence.
  • Remove sequence—Removes the selected transaction sequence.
