LASER_CTRL0
Access: Read/Write
Data Type
USAGE : This register is used to control the laser drive. Bits 5 and 7 require complement values
in register 0x1F. If the registers do not contain complementary values for these bits, the laser is
turned off and the LP_VALID bit in the MOTION register is set to 0. The registers may be written
in any order after the power ON reset.

Description
Rbin Settings
1 = Laser current range from approximately 5mA to 13mA
Match the sensor to the laser characteristics. Set per the bin table specification for the laser in
use based on the bin letter.
Laser calibration mode
- Write 101b to bits [3,2,1] to set the laser to continuous ON (CW) mode.
- Write 000b to exit laser calibration mode, all other valuws are not recommended.
Reading the Motion register (0x03 or 0x42) will reset the value to 000b and exit calibration mode.
LASER force disabled
1 = LASER_NEN output is high
0 = Laser current range from approximately 2mA to 7mA
0 = LASER_NEN functions as normal
