Register Map
There are ten 8-bit registers accessible via I2C. Registers 0x1 and 0x2 define the operation mode of the device. Registers 0x3 through 0x7
store the various ALS/IR/Prox thresholds which trigger interrupt events. Registers 0x8 through 0xA store the results of ALS/IR/Prox ADC
conversions.
