ill ^{Clear, red, green, and blue data is stored as 16-bit values. To ensure the data is read correctly, a two-byte read}
I²C transaction should be used with a read word protocol bit set in the command register. With this operation,
t _{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
G _{s integration cycles end between the reading of the lower and upper registers.}
