LSRPWR_CFG0
Access: Read and Write
Data Type
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.
