Please use [[MCURTC:PublishNotifications|TriggerInterrupt]] to deliver the interrupt mask to the mcu sysmodule unless you wanna filter MCU interrupts, otherwise things like HOME or Power button won&#039;t function. After you no longer need exclusive access and/or exiting the program, use ExitExclusiveInterruptMode ([[MCU_Services#MCU_service_.22mcu::RTC.22|mcu::RTC]] 0x004B0000) to unfreeze the internal event loop.<br /> <br /> Use [[SVC|svcBindInterrupt]] with [[ARM11_Interrupts|InterruptID 0x71]] to create a handle on which you can wait for an MCU interrupt.</div>
