title: UniPhier AIDET
|
|
description: |
|
UniPhier AIDET (ARM Interrupt Detector) is an add-on block for ARM GIC
|
(Generic Interrupt Controller). GIC itself can handle only high level and
|
rising edge interrupts. The AIDET provides logic inverter to support low
|
level and falling edge interrupts.
