Proximity Data Register (0x18 - 0x19h)

Proximity data is stored as a 16-bit value. To ensure the data is

read correctly, a two-byte I²C read transaction should be

utilized with auto increment protocol bits set in the Command

read, the upper eight bits are stored into a shadow register,

which is read by a subsequent read to the upper byte. The upper

ends between the reading of the lower and upper registers.
