+States</title><shortdesc>Describes three power states that are defined by the Kernel.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<ul>
+<li id="GUID-61A3C566-05AA-5F6D-A9DE-B409C873B119"><p> <i>Off</i> - a state
+where the device and all peripherals are powered off or inactive, or are characterised
+by negligible power consumption due to current leakage to the electric and
+electronic circuits that make up the system. This state is achieved as a result
+of controlled system shutdown resulting from a user action, an application
+request, UI inactivity, or as a result of accidental loss of power. This may
+also be achieved as a result of putting the system into a hibernation state.
+Note that a reboot is necessary to return the system to the <i>Active</i> state;
+this could be a cold reboot, or a warm reboot if the system was put into a
+hibernation state. </p> </li>
+<li id="GUID-275417B2-B8C8-5C93-B576-15543D80CAC9"><p> <i>Standby</i> - a
+low power consuming state that results from turning off most system resources
+(clocks, voltages), peripherals, memory banks (where possible), cpu and internal
+logic, while still retaining the state prior to the transition. Typically,
+the only systems that are active are those that are required to detect the
+events that force the transition back to the Active state (e.g. RTC, clocks
+and Peripherals involved in detecting hardware events). Returning to the Active
+state will normally take a far shorter period of time than that required to
+reboot the system. This state is achieved as a result of user action or application
+request. </p> </li>
+<li id="GUID-A31A5A3C-C7C2-5D15-88B2-828F7E5F60D8"><p> <i>Active</i> - the
+fully active state. </p> </li>
+</ul>
+<p>The three power states are defined by the enum values of the <xref href="GUID-87AB8B20-04EE-31D2-8F3D-EA904D05B8D0.dita"><apiname>TPowerState</apiname></xref> enum
+defined in <filepath>e32power.h</filepath>. </p>
