27.7 Sleepwalking

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

In standby, when sleepwalking is on-going:

  • All the power domains are turned on including PD_CORE_RAMρ power domain
  • The low-power mode of the regulators is not activated during sleepwalking
