The logic states of D/CLK and RES determine the type of 1-Wire function to be executed. These signals
are transferred into the DS1481 by activating ENI. This also activates the busy signals.
In Figures 4 through 6 below, during time slots or reset presence sequences the busy lines are active.
Once the busy state is over the computer queries the result of the time slot or reset presence sequence by
generating a falling edge on D/CLK. The result is found on the busy lines until ENI is de-activated.
