 Arduino library for MPU9255 based modules. 
 
 
 Read acceleration, angular velocity and magnetic field strength on your Arduino board using MPU9266 based IMU module connected via the I2C interface. 
 
-## What works ?
+## What works?
 - Acceleration, angular velocity, magnetic field measurements. 
-- Scale selection (from +- 2g , +- 250 dps to +- 16g , +-2000 dps).
+- Dice temperature measurements using build-in sensor.
+- Selectable scale (from +- 2g , +- 250 dps to +- 16g , +-2000 dps).
+- Selectable bandwidth for gyroscope and accelerometer. 
 - Power control (sleep mode, enabling / disabling internal components). 
 - Reset control.
-- Temperature measurements using build-in sensor.
+- Motion interrupt support.

+- Returns: None
+
+Valid output signal modes:
+- `latched_output` - When interrupt is detected, pin will go into active state until interrupt flag is cleared. 
+- `pulse_output` -  When interrupt is detected, pin will generate short pulse. 
+
+-----------------------
+
+`void enable_interrupt_output(interrupts selected_interrupt)`
+
+Enable selected interrupt to propagate to interrupt pin.
