+Example Description
+
+This example describes how to use deep standby api.
+
+Requirement Components:
+    a LED
+    a push button
+    a wakeup pin
+
+Pin name PA_0, PA_5 and PA_22 map to GPIOA_0, GPIOA_5 and GPIOA_22:
+ - PA_5 as input to wakeup the system
+ - PA_0 as output, connect a LED to this pin and ground.
+ - PA_22 as input with internal pull-high, connect a push button to this pin and ground.
+
+In this example, LED is turned on after device initialize.
+User push the button to turn off LED and trigger device enter deep standby mode for 8s.
+If user give failing edge at PA_5 before sleep timeout, the system will resume.
+LED is turned on again after device initialize.
+
+It can be easily measure power consumption in normal mode and deep standby mode before/after push the putton.
