RGBC Channel Data Registers (0x14 − 0x1B)

Clear, red, green, and blue data is stored as 16-bit values. To ensure the data is read correctly, a two-byte read

when the lower byte register is read, the upper eight bits are stored into a shadow register, which is read by a

subsequent read to the upper byte. The upper register will read the correct value even if additional ADC

integration cycles end between the reading of the lower and upper registers.
