Field Name
Description
MOT
Motion since last report or PD
0 = No Motion
1 = Motion occurred, data ready for reading in Delta_X and Delta_Y registers.
Reserved
Reserved for future
FAULT
LED fault detected – set when R_BIN is too low or too high, shorts to VDD or Ground.
0 = No fault
1 = Fault detected
OVFY
Motion overflow Y, Delta_Y buffer has overflowed since last report.
0 = No overflow
1 = Overflow has occurred.
OVFX
Motion overflow X, Delta_X buffer has overflowed since last report.
0 = No overflow
1 = Overflow has occurred.
RES
Resolution in counts per inch
0 = 400
1 = 800
Note: Agilent recommends that registers 0x02, 0x03 and 0x04 be read sequentially.
Delta_X
Address: 0x03
Reset Value: 0x00
Usage: X movement is counts since last report. Absolute value is determined by resolution. Reading
clears the register.
Delta_Y
Address: 0x04
Reset Value: 0x00
Usage: Y movement is counts since last report. Absolute value is determined by resolution. Reading
clears the register.

Usage: Register 0x0a allows the user to change the configuration of the sensor. Shown below are the
bits, their default values, and optional values.
Field Name
Description
RESET
Power up defaults (bit always reads 0)
0 = No effect
1 = Reset registers and bits to power up default settings (bold entries)
LED_MODE
LED shutter Mode
0 = Shutter mode off ( LED always on ) ( even if no motion up to 1sec.)
1 = Shutter mode on (LED only on when the electronic shutter is open)
Sys Test
System tests (bit always reads 0)
0 = No tests
1 = perform all system tests, output 16 bit CRC via Data_Out_Upper and
Data_Out_Lower registers.
