Notes:
1) When reading ALS data registers, read sequence should always be from lower address to higher address (E.g. For ALS
data, Ch1 data should be read first followed by Ch0 data. Read sequence should be 0x88, 0x89, 0x8A, 0x8B. When 0x8B is
read, all four ALS data registers will be populated with new set of data).
2) When setting of INTERRUPT register (addr 0x8F) is necessary, it should be done before the device is in Active mode.
