8.9 Serial interface
The serial interface of the PCF8563 is the I2C-bus. A detailed description of the
I2C-bus specication, including applications, is given in the brochure:
The I2C-bus
and how to use it, order no. 9398 393 40011 or I2C Peripherals Data Handbook IC12.
8.9.1
Characteristics of the I2C-bus
The I2C-bus is for bidirectional, two-line communication between different ICs or
modules. The two lines are a serial data line (SDA) and a serial clock line (SCL). Both
lines must be connected to a positive supply via a pull-up resistor. Data transfer may
be initiated only when the bus is not busy.
message is a ‘transmitter’, a device receiving a message is the ‘receiver’. The device
that controls the message is the ‘master’ and the devices which are controlled by the
master are the ‘slaves’.
8.9.2
START and STOP conditions
Both data and clock lines remain HIGH when the bus is not busy. A HIGH-to-LOW
transition of the data line, while the clock is HIGH is dened as the start condition (S).
A LOW-to-HIGH transition of the data line while the clock is HIGH is dened as the
stop condition (P); see Figure 7.
