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. |
