+Description:
+		Accelerometer power mode. Setting this attribute will set the
+		requested power mode to use if the ODR support it. If ODR
+		support only 1 mode, power mode will be enforced.
+		Reading this attribute will return the current accelerometer
+		power mode if the sensor is on, or the requested value if the
+		sensor is off. The value between real and requested value can
+		be different for ODR supporting only 1 mode.
