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
.
9.3 System configuration
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 (see
Figure 8
).
9.4 Acknowledge
The number of data bytes transferred between the start and stop conditions from
transmitter to receiver is unlimited. Each byte of eight bits is followed by an
acknowledge bit. The acknowledge bit is a HIGH-level signal put on the bus by the
transmitter during which time the master generates an extra acknowledge related
