Figure 9 illustrates that the sum of TINIT, TRC, and TSAMPLE must be less than 15
s for a read time slot.
Figure 10 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
s period.
