This property specifies the interrupt request value for a Board IO Device or Task. The IRQ value determines the priority a Board IO Device or Tasks has when requesting an interrupt.
By default, the IRQ is set to 0.
This property is set:
• For Board IO Devices - on the Options tab of a Board IO Device's Property Pages.
• For Tasks - on the Interrupt tab of a Task's Property Pages. Note that for Tasks, you can set the IRQ only after selecting the Interrupt Handler check box.
If you select the Proprietary\Board IO Devices folder in the Dictionary pane, the Contents pane allows you to view the IRQ values of all Board IO Devices in the model.
