9 / 18 page  ISL12057 FN6755 Rev 2.00 Page 9 of 18 Sep 25, 2015 Real-Time Clock Registers Addresses [00h to 06h] RTC REGISTERS (SC, MN, HR, DW, DT, MO, YR) These registers depict BCD representations of the time. As such, SC (Seconds, address 00h) and MN (Minutes, address 01h) range from 0 to 59, HR (Hour, address 02h) can either be a 12-hour or 24-hour mode, DW (Day of the Week, address 03h) is 1 to 7, DT (Date, address 04h) is 1 to 31, MO (Month, address 05h) is 1 to 12, and YR (Year, address 06h) is 0 to 99. 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, 1-2-3-4-5-6-7-1-2-… The assignment of a numerical value to a specific day of the week is arbitrary and may be decided by the system software designer. 24-HOUR TIME If the MIL bit of the HR register is “0”, the RTC uses a 24-hour format, and bit 5 of the HR register is the second 10-hour bit (20–23 hours). If the MIL bit is “1”, the RTC uses a 12-hour format and bit 5 of the HR register is the AM/PM bit, with logic high being PM. The clock defaults to 24-hour format time. CENTURY INDICATOR The century bit (bit 7 of the MO register) is toggled when the years register overflows from 99 to 00 to indicate the change of century. 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 ISL12057 does not correct for the leap year in the year 2100. Addresses [0Eh to 0Fh] The Control and Status Registers consist of the Status Register, Interrupt, and Alarm Register. TABLE 1.
