Data Type : 8 Bit unsigned

USAGE : This register is used to set the laser current. It is to be used together with register 0x1D,

where register 0x1D contains the complement of register 0x1C. If the registers do not contain

complementary values, 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.

Field Name

LP7 LP0

Description

Controls the 8-bit DAC for adjusting laser current.

One step is equivalent to (1/384)*100% = 0.26% drop of relative laser current.

Refer to the table below for examples of relative laser current settings.

Data Type : 8 Bit unsigned

USAGE : The value in this register must be a complement of register 0x1C for laser current to be

as programmed, otherwise the laser is turned off and the LP_VALID bit in the MOTION register is

set to 0. Registers 0x1C and 0x1D may be written in any order after power ON reset.
