interrupts will be lost in this scenario). When an edge interrupt is triggered, CIRQ will record the status and generated a pulse signal to GIC when flush command is executed. With CIRQ, MCUSYS can be completely turned off to improve the system power consumption without losing interrupts. Youlin Pei
