+title: Freescale i.MX8qxp Display Controller interrupt controller
+
+description: |
+ The Display Controller has a built-in interrupt controller with the following
+ features for all relevant HW events:
+
+ * Enable bit (mask)
+ * Status bit (set by an HW event)
+ * Preset bit (can be used by SW to set status)
+ * Clear bit (used by SW to reset the status)
+
+ Each interrupt can be connected as IRQ (maskable) and/or NMI (non-maskable).
+ Alternatively the un-masked trigger signals for all HW events are provided,
+ allowing it to use a global interrupt controller instead.
+
+ Each interrupt can be protected against SW running in user mode. In that case,
+ only privileged AHB access can control the interrupt status.
