LSRPWR_CFG0
Access: Read and Write
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.
LSRPWR_CFG1
Access: Read and Write
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
