General description
The PCF85063ATL is a CMOS1 Real-Time Clock (RTC) and calendar optimized for low power consumption.
An offset register allows fine-tuning of the clock.
All addresses and data are transferred serially via the two-line bidirectional I2C-bus.
Maximum data rate is 400 kbit/s.
The register address is incremented automatically after each written or read data byte.
