8.6.4
Both data and clock lines will 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 a START condition (S). A LOW-to-HIGH transition of the data line while the clock is HIGH
is defined as a STOP condition (P) (see Fig.12).
8.6.5
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’.
