Real Time Clock Registers
Addresses [00h to 07h]
RTC REGISTERS (SC, MN, HR, DT, MO, YR, DW, SS)
These registers depict BCD representations of the time. As
such, SC (Seconds) and MN (Minutes) range from 0 to 59, HR
(Hour) can be either 12-hour or 24-hour mode, DT (Date) is 1
to 31, MO (Month) is 1 to 12, YR (Year) is 0 to 99, DW (Day of
the Week) is 0 to 6, and SS (Sub-Second) is 0 to 9. The Sub-
Second register is read-only and will clear to “0” count each
time there is a write to a register in the RTC section.
The DW register provides a Day of the Week status and uses
three bits DW2 to DW0 to represent the seven days of the
week. The counter advances in the cycle 0-1-2-3-4-5-6-0-1-
2.... The assignment of a numerical value to a specific day of
the week is arbitrary and may be decided by the system
software designer. The default value is defined as “0”.
24 HOUR TIME
If the MIL bit of the HR register is “1”, the RTC uses a
24-hour format. If the MIL bit is “0”, the RTC uses a 12-hour
format and HR21 bit functions as an AM/PM indicator with a
“1” representing PM. The clock defaults to 12-hour format
time with HR21 = “0”.
LEAP YEARS
Leap years add the day February 29 and are defined as those
years that are divisible by 4. Years divisible by 100 are not leap
years, unless they are also divisible by 400. This means that
the year 2000 is a leap year and the year 2100 is not. The
ISL12032 does not correct for the leap year in the year 2100.
Status Registers (SR)
Addresses [08h to 09h]
The Status Registers consist of the DC and AC status
Status Register (SRDC)
The Status Register DC is located in the memory map at
address 08h. This is a volatile register that provides status of
RTC failure (RTCF), Battery Level Monitor (LBAT85,
LBAT75), VDD level monitor (LVDD), Alarm0 or Alarm1
trigger, Daylight Saving Time adjustment, and Battery active
mode.
