Clock and Calendar
The time and calendar information is obtained by read-
ing the appropriate register bytes. Table 2 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 device can
be run in either 12-hour or 24-hour mode. Bit 6 of the
Hours register is defined as the 12-hour 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 20-hour bit
(20–23 hours). The century bit (bit 7 of the Month regis-
ter) is toggled when the Years register overflows from 99
Table 2. Timekeeping Registers
Note: Unless otherwise specified, the registers’ state is not defined when power is first applied.
