PXI Express Configuration Information
If the Supports PXI Express features box is checked, the next window is the PXI Express Configuration window. PXI Express requires devices to be able to report their slot number. Using this window, you can specify the steps required to query this value from the device.
PXI Express Configuration Information
Typically, requesting the slot number from a device involves reading a register. This may involve multiple steps, as a single register may have multiple purposes depending on the last value written to it, or the state of other registers. To add a step, click the Add a step before or Add a step after button. The steps to query the slot number from your device that supports PXI Express features should be in the device register documentation.
After selecting one of the Add a step buttons, the PXI Express Information window appears. The following figure specifies that to get the slot number, you you must read a 32-bit value from BAR0 at offset 0x14. The Read Mask and Bits to Shift values are used, frequently in combination, to select specific bits that represent the slot number when the value returned by a register contains more information than just a slot number. Again, this information is provided for example purposes only and is not useful when attempting to handle interrupts for the PXI-6070E. Click OK when you finish entering a particular register access step.
