Address Map
Table 3 shows the DS1340 address map. The RTC reg-
isters are located in address locations 00h to 06h, and
the control register is located at 07h. The trickle-charge
and flag registers are located in address locations 08h
to 09h. During a multibyte access of the timekeeping
registers, when the address pointer reaches 07h—the
end of the clock and control register space—it wraps
around to location 00h. Writing the address pointer to
the corresponding location accesses address locations
08h and 09h. After accessing location 09h, the address
pointer wraps around to location 00h. On a I2C START,
STOP, or address pointer incrementing to location 00h,
the current time is transferred to a second set of regis-
ters. 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 the
main registers update during a read.
Clock and Calendar
The time and calendar information is obtained by read-
ing the appropriate register bytes. Table 3 shows the
RTC registers. The time and calendar data are set or
initialized by writing the appropriate register bytes. The
contents of the time and calendar registers are in the
binary-coded decimal (BCD) format. The day-of-week
