8.9 Serial interface
The serial interface of the PCF8563 is the I
2
C-bus. A detailed description of the
I
2
C-bus specification, including applications, is given in the brochure: The I
2
C-bus
and how to use it order no. 9398 393 40011 or I
2
C Peripherals Data Handbook IC12.
8.9.1
Characteristics of the I
2
C-bus
The I
2
C-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.
The I
2
C-bus system configuration is shown in
Figure 6
. A device generating a
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 defined as the start condition (S).
A LOW-to-HIGH transition of the data line while the clock is HIGH is defined as the
stop condition (P); see
Figure 7
.
