The Status Register provides the internal status of the device. This register is read only.
ALS clear and IR data are stored as two 16-bit values. To ensure the data is read correctly, a two-byte read I
transaction should be used 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 in 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.
Proximity data is stored as a 16-bit value. To ensure the data is read correctly, a two-byte read I
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.
