In this section
This section describes some basic I2C data fields, which are all static.
The field at address 0x14, length 0x10 (16 bytes) gives the name of the vendor, which in the example is "SumitomoElectric".
The DDM options field is located at address 0x5C, length 0x01 (1 byte). The value in the example is 0x68, or in binary notation, 01101000, where the values of the individual bits in the example have the following interpretation:
01101000 ||||_____ Bit 3: Optical average power is indicated. |||______ Bit 4: External calibration is not used. ||_______ Bit 5: Internal calibration is used. |________ Bit 6: DDM is implemented.
