INT_SET: Interrupt register / INT output.

In bit #6 and #5 the trigger source for the last interrupt event is stated. Data from status register (0x8E) are used. In latched mode

(set by bit #3) this remains unchanged until the interrupt register has been read by the MCU. Afterwards the bits are reset

automatically to “0” by the SFH 7773. In unlatched mode it is updated after every measurement. The output polarity of the interrupt

function can be changed by bit #2. The interrupt can be triggered by an ambient light sensor event and / or by a proximity sensor

event (bit #1 and bit #0). Z-state means the output is in high-impedance state.
