Register Configuration
1. Real-time data register
The real-time data register is a 56-bit register that stores the BCD code of the year, month, day, day of
week, hour, minute, and second data. Any read/write operation performed by the real-time data access
command transmits or receives the data from the LSB which is the first digit of the year.
Year data (00 to 99)
Month data (01 to 12)
Day data (01 to 31)
Day of week data (00 to 06)
A septenary counter. Set it so that it corresponds
to the day of the week.
Hour data (00 to 23 or 00 to 11)
Minute data (00 to 59)
Second data (00 to 59)
AM/PM: For 12-hour expression, 0: AM, 1: PM
For 24-hour expression, this flag has no
meaning but either “0” or “1” must be
written.
Sets the lower two digits of the Western
Calendar Year (00 to 99) and links together with
the auto calendar feature until 2099.
The count value is automatically changed by the
auto calendar feature.
1 to 31: 31-day months (1, 3, 5, 7, 8, 10, 12)
1 to 30: 30-day months (4, 6, 9, 11)
1 to 29: Feb. (leap year)
