Proximity Data Register (0x18 − 0x19h)

should be utilized with auto increment protocol bits set in the command register. With this operation, 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 the next ADC cycle ends between

the reading of the lower and upper registers.
