Register 0x02 allows the user to determine if motion has occurred since the last time it was read. If
so, then the user should read registers 0x03 and 0x04 to get the accumulated motion. It also tells if
the motion buffers have overflowed since the last reading. The current resolution is also shown.
Notes
Reading this register freezes the Delta_X and Delta_Y register values. Read this register before
reading the Delta_X and Delta_Y registers. If Delta_X and Delta_Y are not read before the motion
register is read a second time, the data in Delta_X and Delta_Y will be lost.
