5.2.1. Interrupt Enable
The Interrupt Enable box specifies which events cause the Si3452 to generate an interrupt.
Figure 15. Interrupt Enable Box
5.2.2. Events
The Events box displays the status of the interrupt line and the port events.
Figure 16. Events Box
If the interrupt line is active, then the LED bar at the top of the Events box is bright red instead of dark red. Note
that if there are multiple Si3452 controllers in the system, one or more of these controllers may be pulling the
interrupt line low. It may not be the currently-selected Si3452 that is making the interrupt line active.
The Port Events registers can be read using the port event buttons under the Interrupt line active LED bar. Further
below the port event, LEDs display the status of each event for each port. If a port event is active, then the
corresponding LED is bright red.
The user may manually update a port's event LEDs by clicking on the port's event button (P1, P2, P3, P4). The GUI
reads the corresponding Port Events register and updates the port's event LEDs. Port event LEDs are not updated
by polling or by the “Refresh” button unless the CoR check box is checked.
If a port event bit is set in the interrupt register, then the corresponding port event button (P1, P2, P3, P4) is red.
This indicates that the port's event LEDs are stale and that the Port Events register should to be read. Reading a
Port Events register has the side effect of clearing that Port Events register and clearing the port event bit in the
interrupt register, consequently making the port event button no longer red.
