Address Map
Table 2 shows the address map for the registers of the DS1371. During a multibyte access, when the
address pointer reaches the end of the register space (08h), it wraps around to location 00h. On a 2-wire
START, STOP, or address pointer incrementing to location 00h, the current time is transferred to a
second set of registers. The time information is read from these secondary registers, while the clock may
continue to run. This eliminates the need to reread the registers in case of an update of the main registers
during a read.
