release the bus by the end of the time slot, and the bus will be pulled back to its high idle state by the
pullup resister. Output data from the DS18S20-PAR is valid for 15
ms after the falling edge that initiated
the read time slot. Therefore, the master must release the bus and then sample the bus state within 15
ms
from the start of the slot.
Figure 13 illustrates that the sum of TINIT, TRC, and TSAMPLE must be less than 15
ms for a read time slot.
Figure 14 shows that system timing margin is maximized by keeping TINIT and TRC as short as possible
and by locating the master sample time during read time slots towards the end of the 15
ms period.
