Register Description
The device includes 16 registers which are used to control functions such as the RTC, Status, Alarm,
Frequency output etc. There are also five bytes of EEPROM which contain the clock compensation
settings and stored user data. The RTC and Alarm register data is stored in BCD format, while other
data is stored in binary format. The register map shows the address definitions for the I
2C interface.
The command byte and R/W bit are used for the 3-wire interface.
