+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.
