Figure 7-35 and Figure 7-36 show exaggerated views of the Ready Signal to describe the difference in access
times to write or read to or from various memory locations on the DS3170 device. Some registers will have a faster
access time than others and if needed, the user can implement the RDY signal to maximize efficiency of read and
write accesses.
