Product data sheet
8.1.1.1 START and STOP conditions
8.1.2 System configuration
Both data and clock lines remain HIGH when the bus is not busy. A HIGH-to-LOW change
of the data line, while the clock is HIGH, is defined as the START condition (S).
A LOW-to-HIGH change of the data line, while the clock is HIGH, is defined as the STOP
condition (P). The START and STOP conditions are illustrated in
A device generating a message is a ‘transmitter’ and 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’. The system configuration is illustrated in
