Data Type
USAGE : This register is used to control the laser drive. Bits 7 and 6 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
R
00= Laser current range from approximately 0.9mA to 3mA
01= Laser current range from approximately 2mA to 5mA
11 = Laser current range from approximately 4mA to 10mA
10 = Invalid setting, LPVALID will be set and laser will off.
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 values are not recommended.
Reading the Motion register (0x02 or 0x42) will reset the value to 000b and exit
calibration mode.
LASER force disabled
0 = LASER_NEN functions as normal
1 = LASER_NEN output is high.
