ADDRESS MAP
Figure 6 shows the address map for the DS1339 registers. During a multibyte access, when the address pointer
reaches the end of the register space (10h), it wraps around to location 00h. On an I
C 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 re-read the registers in case of an update of the main registers during a read.
