Data Sheet
PT7C43390
2-Wire Real-time Clock Module
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)
Sets the lower two digits of the Western Calendar
Year (00 to 99) and links together with the auto
calendar feature until 2099.
Month data (01 to 12)
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)
1 to 28: Feb. (common year)
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)
AM/PM
For a 12-hour expression, write 0 and 1 for AM and
PM, respectively.
For a 24-hour expression, either 0 or 1 can be written. 0
is read when the hour data is from 00 to 11, and 1 is
read when from 12 to 23.
Minute data (00 to 59)
Second data (00 to 59)
