Data Type: Bit field.
Usage:
Typically in the motion detection routine, the host controller will poll the sensor for valid motion data by checking the Motion bit.
If the Motion bit is set, the motion data in Delta_X and Delta_Y registers are valid and ready to be read. Be sure to read Motion
bit first before reading out Delta_X and Delta_Y registers. DXOVF bit and DYOVF bit show whether if the motion report buffers
have overflowed since last read out.
Field Name
Motion

Description
Motion detected since last report
0 = No motion (Default)
1 = Motion detected, data in Delta_X and Delta_Y registers are valid and ready to be read out
Delta_Y overflowed since last read out
0 = No overflow (Default)
1 = Overflow occurred
Delta_X overflowed since last read out
0 = No overflow (Default)
1 = Overflow occurred
