The PCF8563 is a CMOS real-time clock/calendar optimized for low power consumption.
A programmable clock output, interrupt output and voltage-low detector are also provided.
All addresses and data are transferred serially via a two-line bidirectional I2C-bus.
Maximum bus speed is 400 kbit/s. The built-in word address register is incremented
automatically after each written or read data byte.
