26.5.2 Power Management
All interrupts are available in all sleep modes, but the EIC can be configured to automatically mask some interrupts in order to prevent device wake-up.
The EIC will continue to operate in any sleep mode where the selected source clock is running. The EIC’s interrupts can be used to wake up the device from sleep modes. Events connected to the Event System can trigger other operations in the system without exiting sleep modes.
