25.6.8 Sleep Mode Operation

The EIC will continue to operate in any sleep modes where the selected source clock is running. In sleep modes, an EXTINTx pin can wake up the device if the corresponding condition matches the configuration in the CONFIGn register, and the corresponding bit in the Interrupt Enable Set register (INTENSET25.7.7 Interrupt Enable Set) is written to '1'. Conversely, the EIC can be configured to automatically mask some interrupts to prevent device wake-up.

Events connected to the Event System can trigger other operations in the system without exiting sleep modes.
