Power management

As demands for flexible power management has increased for realizing more battery efficient solutions, a new group of power management functions are available which implements the possibilities to control the power usage of the RTCU. The new features offer the application to stop executing and wait for an event to occur before proceeding operation from the location where the program was stopped. Another feature is control of the RTCU execution speed and how the device should behave when an external power fail occurs.

Low power mode power management functions:

	•pmPowerDown	Power down the device and reset when an event happens.
	•PowerDown	Powers the device down for a certain number of seconds.
	•pmWaitEvent	Makes device sleep until an event happens by entering a power saving sleep mode.

	•pmSuspend	Makes device sleep until an event happens by entering a power saving sleep mode.
	•pmGetWakeSource	Converts the return code from pmSuspend into usable values.
	•pmGetWakeSourceString	Converts the return code from pmSuspend into a string for debugging.

Functions for control of vibration detection:

	•pmSetVibrationsensitivity	Sets the sensitivity of the Vibration sensor.
	•pmVibration	Query whether vibration has been detected since last call.

Power management functions for control of the power usage.

	•pmExternalPower	Enable/disable the external power to run on battery.
	•pmGetPowerFail	Returns the device behavior when external power fails.
	•pmPowerFail	Sets device behavior when external power fails.
	•pmSetSpeed	Control the speed of execution.

Sleep functions.

	•DeepSleep	Makes the device sleep for a number of milliseconds by entering power saving sleep mode.
	•pmDeepSleep	Makes the device sleep for a number of milliseconds by entering power saving sleep mode.
	•Sleep	Makes the device sleep for a number of milliseconds.
