ALS_DATA_CH0 Register (0x8A / 0x8B) (Read Only)
These two registers should be read after reading channel-1 data (from registers 0x88, 0x89). Lower address register
should be read first (i.e. read 0x8A first, then read 0x8B). See ALS_DATA_CH1 register information above. The ALS ADC
channel-0 data is expressed as a 16-bit data spread over two registers. The ALS_DATA_CH0_0 and ALS_DATA_CH0_1
registers provide the lower and upper byte respectively.
