16.6.3 SleepWalking

SleepWalking is the capability for a device to temporarily wake-up clocks for the peripheral to perform a task without waking-up the CPU in STANDBY sleep mode. At the end of the sleepwalking task, the device can either be awakened by an interrupt (from a peripheral involved in SleepWalking) or enter into STANDBY sleep mode again.

In this device, SleepWalking is supported only on GCLK clocks by using the on-demand clock principle of the clock sources. Refer to On-demand, Clock Requests for more details.
