PARTNO
The ADC data is expressed as a 16-bit word stored in two 8-bit registers. The read-only ADC data registers
DATALOW and DATAHIGH provide the low and high bytes, respectively, of the 16-bit ADC conversion value.
The conversion value translates directly to units of lux.
The ID register is a read-only register that provides the value for the part number. The PARTNO field indicates
the part number of each device given in the Available Options section and will remain constant.
FIELD
The ID register is useful for validating the device type and for verifying the functionality of the interface. When
used for this purpose, it is recommended that the Reserved field be masked out as follows:
Value = ID AND 0xF0, where AND represents a bit-wise AND function
