I2C-bus protocol
Addressing: Before any data is transmitted on the I2C-bus, the device which should
respond is addressed rst. The addressing is always carried out with the rst byte
transmitted after the start procedure.
The PCF8563 acts as a slave receiver or slave transmitter. Therefore the clock signal
SCL is only an input signal, but the data signal SDA is a bidirectional line.
The PCF8563 slave address is shown in Figure 10.
Clock/calendar read/write cycles: The I2C-bus conguration for the different
PCF8563 read and write cycles are shown in Figure 11, 12 and 13. The word
address is a four bit value that denes which register is to be accessed next. The
upper four bits of the word address are not used.
