Sensor Command Register
The bits in the command register are organized as follow:
Bit #
Value
Label
Description
0-1
0, 2 or 3
Sensor orientation
0: set sensor orientation to be right sensor
2: set sensor orientation to be left sensor
3: set sensor orientation to be center sensor
2
0/1
Sensing mode
0: set the sensing mode to be edge mode
1: set the sensing mode to be contrast mode
3-5
0-7
Analog mode
0: Analog output is disabled.
1: Analog output is enabled and zero scale voltage/current is output.
Note: This mode can be used during calibration while connecting the
controller to a third-party controller that requires calibration. During the
calibration, this mode can be selected to calibrate for zero scale output.
2: Analog output is enabled and full scale voltage/current is output.
Note: This mode can be used during calibration while connecting the
controller to a third-party controller that requires calibration. During the
calibration, this mode can be selected to calibrate for full scale output.
3: Analog output is enabled and the analog output corresponds to the left
edge position.
