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.

Usage
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.
Field Name Description
Motion
Motion since last report or PD
0 = No motion (Default)
1 = Motion occurred, data ready for reading in Delta_X and Delta_Y registers
Reserved[1:0] Reserved for future use
DYOVF

RES[2:0]
Motion Delta Y overflow, ΔY buffer has overflowed since last report
0 = No overflow (Default)
1 = Overflow has occurred
Motion Delta X overflow, ΔX buffer has overflowed since last report
0 = No overflow (Default)
1 = Overflow has occurred

X movement is counts since last report. Absolute value is determined by resolution. Reading clears
the register. Report range –128 ~ +127.
Delta_Y
76543210
Y7 Y6 Y5 Y4 Y3 Y2 Y1 Y0
Y movement is counts since last report. Absolute value is determined by resolution. Reading clears
the register. Report range –128 ~ +127.
