Note:
Unless otherwise specified, the state of the registers is not defined when power (V
CC
and V
BACKUP
) is first applied.
X = General-purpose read/write bit.
0 = Always reads as a zero.
Clock and Calendar
The time and calendar information is obtained by read-
ing the appropriate register bytes. Figure 5 illustrates
the RTC registers. The time and calendar are set or ini-
tialized by writing the appropriate register bytes. The
contents of the time and calendar registers are in the
binary-coded decimal (BCD) format. The end of the
month date is automatically adjusted for months with
fewer than 31 days, including corrections for leap years
through 2099. The day-of-week register increments at
midnight. Values that correspond to the day-of-week
are user-defined but must be sequential (i.e., if 1
equals Sunday, then 2 equals Monday, and so on).
Illogical time and date entries result in undefined oper-
ation. The DS1388 can be run in either 12-hour or 24-
hour mode. Bit 6 of the hours register is defined as the
12- or 24-hour mode-select bit. When high, the 12-hour
mode is selected. In the 12-hour mode, bit 5 is the
AM
/PM bit with logic-high being PM. In the 24-hour
mode, bit 5 is the second 10-hour bit (20–23 hours).
Changing the 12/
24
bit requires that the hours data be
re-entered in the proper format.
