*The optimal sampling point for the master is as close as possible to the end time of the t
RDV
period
without exceeding t
RDV
. For the case of a Read-one time slot, this maximizes the amount of time for the
pull-up resistor to recover the line to a high level. For a Read-zero time slot it ensures that a read will
occur before the fastest 1-Wire device(s) release the line (t
RELEASE
= 0).
