Data Type
:
8-bit unsigned integer
USAGE: This register is used to set the laser current and bin matching parameter. It is to be used together with register
0x2D where register 0x2D must contain the complement of register 0x2C in order for the laser current to be pro-
grammed. Writing to this register causes a fault test to be performed on the XY_LASER pin. The test checks for stuck
low and stuck high conditions. During the test, LASER_NEN will be driven high and XY_LASER will pulse high for 12us
and pulse low for 12us (times are typical). Both pins will return to normal operation if no fault is detected.

Data Type
:
8-bit unsigned integer
USAGE: The value in this register must be a complement of register 0x2C for laser current to be as programmed, oth-
erwise the laser current is set to 33.85%. Registers 0x2C and 0x2D may be written in any order after power ON reset
or SROM download.

Description
Match the sensor to the VCSEL characteristics. Set per the bin table specification for the
VCSEL bin in use.
Controls the 7 bit DAC for adjusting laser current.One step is equivalent to (1/192)*100% =
0.5208% drop of relative laser current.Refer to the table below for example of relative laser
current settings.
