1. general description
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 address and data are transferred serially via a two-line
bidirectional i2c-bus. maximum bus speed is 400 kbits/s. the built-in word address
register is incremented automatically after each written or read data byte.
