Proximity Data Registers (0x18 − 0x19)

Proximity data is stored as a 16-bit value. When the lower byte is read, the upper byte is latched into a shadow

register. The shadow register ensures that both bytes are the result of the same proximity cycle, even if

additional proximity cycles occur between the lower byte and upper byte register readings. The simplest way

in the Command register TYPE field.
